| caodepalha | hi everyone i got a bit of a problem here. a few days ago i was messing around with instalations in the terminal and being a total newbie somehow i managed to get my aplications menu all mixed. is it possible to get it back the way it was? | 02:33 |
| Unit193 | Missing things or what? Look in ~/.local/share/applications/ | 02:50 |
| caodepalha | i dunno really | 02:51 |
| caodepalha | no nothing is missing | 02:55 |
| caodepalha | all the audio related apps wnet to the multimedia folder | 03:05 |
| Unit193 | Is there anything in ~/.local/share/applications/ ? And are you in the right session? | 03:10 |
| caodepalha | yes | 03:28 |
| Unit193 | As those files are local modifications, you can try to (re)move them and see if it changes. | 03:30 |
| caodepalha | where exactly can i find that folder? | 03:30 |
| Unit193 | ~/ means your home dir, so /home/caodepalha/ the dot in front of local means it's a hidden dir. | 03:32 |
| caodepalha | ok! got a mimeapps.list file | 03:34 |
| caodepalha | would that be the file? | 03:39 |
| Unit193 | In a way, what opens what. | 03:41 |

| caodepalha | any help? | 04:14 |
| holstein | caodepalha: whats up? | 04:14 |
| caodepalha | i'm a total newbie to ubuntu | 04:15 |
| caodepalha | i have ubuntu studio installed a few weeks ago | 04:15 |
| holstein | caodepalha: whats wrong with the applications menu? | 04:15 |
| caodepalha | the other day i was messing aroung with instalations and somehow my aplications menu got all mixed | 04:16 |
| holstein | caodepalha: what do i suggest? if you want it back "as default", reinstall.. that usually takes about 10 minutes or so | 04:16 |
| caodepalha | things are out of place | 04:16 |
| caodepalha | for example if i go to the multimedia menu | 04:16 |
| caodepalha | everything is there mixed | 04:16 |
| holstein | then, plan for failure, since you are abviously experimenting.. experiement with a virtualbox install or with a live CD.. or with a new test user | 04:16 |
| holstein | or, stop using the menu.. i dont use it | 04:16 |
| holstein | !info kupfer | 04:16 |
| ubottu | kupfer (source: kupfer): fast and lightweight desktop summoner/launcher. In component universe, is optional. Version 0+v208-2 (raring), package size 810 kB, installed size 2862 kB | 04:17 |
| holstein | ^^ i use that, and i literallly could care less where applications have gone | 04:17 |
| caodepalha | how to do call the apps? | 04:17 |
| caodepalha | *do you | 04:17 |
| caodepalha | in the terminal? | 04:17 |
| holstein | caodepalha: with the software i mentioned, called kupfer.. above | 04:17 |
| holstein | caodepalha: you can edit your current menu.. remove the config files from the user /home.. reinstall.. you have plenty of options | 04:18 |
| OvenWerks | sounds like logged into xfce session | 04:20 |
| holstein | yup.. something simple.. | 04:20 |
| holstein | or the ubuntustudio-menu meta removed.. | 04:20 |
| caodepalha | i was looking into kupfer | 04:20 |
| OvenWerks | nope, it doen't exist yet again :) | 04:21 |
| caodepalha | what about removing the config files? | 04:21 |
| holstein | caodepalha: see if you are logged into the xfce session instead of the ubuntustduio one | 04:21 |
| caodepalha | well i'd really like to have it like it was before | 04:21 |
| OvenWerks | rm -r ~/.config | 04:21 |
| caodepalha | i should be messing around being a newbie | 04:21 |
| holstein | caodepalha: ? | 04:21 |
| caodepalha | what will taht command do? | 04:21 |
| holstein | caodepalha: you can "mess around" all you want | 04:21 |
| caodepalha | souldn't | 04:21 |
| caodepalha | shouldn't' | 04:22 |
| holstein | caodepalha: that command does what you asked.. removes the config files.. which could reset what you are wanting reset | 04:22 |
| OvenWerks | logout to the login screen and make sure it says ubuntustudio in one of the boxes. If it says xfce, click on that and it should drop down a menu to select unbuntustudio | 04:23 |
| Unit193 | May as well hit the cache too. | 04:23 |
| OvenWerks | ya, that would be next | 04:24 |
| OvenWerks | But what he described sounds like wrong session | 04:24 |
| OvenWerks | that is something I am trying to fix for 13.10 | 04:24 |
| Unit193 | Yeah, a little. Asked, but not sure if it was an answer to another Q. | 04:25 |
| caodepalha | thank you thank you thank you | 04:25 |
| OvenWerks | :) | 04:25 |
| OvenWerks | Glad I could help | 04:25 |
| OvenWerks | Just walked in the door | 04:25 |
| caodepalha | This is great! | 04:27 |
| solarbird | hey, anybody else on a USB sound device and Ubuntu Studio 12.04 LTS seen their bus performance die in a fire since the updates that came down... well, I pulled them down through apt-get about 10 days ago? | 06:07 |
| solarbird | i'm running jack+ardour and i've had to kick my audio latency up to 279ms to be able to use the machine at all. It's not CPU (3Ghz quad-core, averaging 76% idle), it's not RAM (I'm not close to swapping). vmlinuz-3.2.0-49-lowlatency kernel. | 06:09 |
| solarbird | so this kind of implies... that there's something atomic _somewhere_... that is processed faster in the generic kernal than in the low-latency kernel, which is slower due to the handoffs it does internally to be closer to realtime... which causes XRUNs to show up sooner in low-latency than in generic. BUT: it's something that changed in that 10-days-ago round of Ubuntu updates, wherein several libraries got updated. (But of | 06:52 |
| solarbird | But that's just hypothesis. | 06:54 |
| Hyuri | help me please =( | 06:58 |
| Hyuri | i've just installed ubuntu studio and selected "install alonside windows 7" but my partition got deleted! | 06:58 |
| Hyuri | 900 GB of data, the entire partition has gone | 06:59 |
| Hyuri | no windows 7 neither | 06:59 |
| Hyuri | i am lost | 07:01 |
| Hyuri | the PC is not mine | 07:01 |
| Hyuri | 900 GB of captured videos and a i have to start editing a new video tomorrow | 07:01 |
| cub | Hyuri, sounds bad. i need to change computer but will be back. In the mean time perhaps someone else might be able to help you. | 07:02 |
| Hyuri | ok, thanks | 07:02 |
| cub | Unit193, do you have a moment to take a look at Hyuri 's issue? | 07:07 |
| Unit193 | Hyuri: Don't touch it, don't repartition it, do nothing. What you need to do is boot off a live medium and run testdisk, see if it can detect the deleted partitions and re-write them to disk. If not, it may be able to recover files to an external drive. | 07:08 |
| Hyuri | ok | 07:09 |
| Hyuri | testdisk is a commandline function? | 07:10 |
| Unit193 | Yes. | 07:11 |
| Unit193 | http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step for example. | 07:12 |
| Hyuri | thanks | 07:12 |
| cub | Thanks for stepping in Unit193, I felt it was a bit too deep water for me..:) | 07:15 |
| Hyuri | many, many thanks | 07:15 |
| Unit193 | cub: Had to use testdisk once when a windows partition edit went very, very wrong. | 07:15 |
| Unit193 | Hyuri: Getting it? | 07:15 |
| Hyuri | the infos are giving hope to me | 07:16 |
| Hyuri | what a crazy problem. Is that "common"? | 07:21 |
| cub | Hyuri, it should be fixable. I once removed my entire backup disk containing all photos the family had taken. It was some nervous hours but everything was recovered. :D | 07:21 |
| Hyuri | =) | 07:21 |
| Hyuri | feeling a little better now | 07:22 |
| Hyuri | maybe the problem is because have 2 HDDs here and both had windows 7 installed. Maybe Ubuntu Studio got confused? | 07:23 |
| cub | Huh? It confuses me at least. You have two physical drives with one Windows OS installation each? | 07:24 |
| cub | Or are they c: for system and d: for data? | 07:25 |
| Hyuri | both had windows 7 each | 07:26 |
| Hyuri | now, just one =( | 07:26 |
| Hyuri | and the wrong one... -.-" | 07:26 |
| cub | hmm | 07:26 |
| Hyuri | i don't know why. The owner of this PC are really crazy | 07:26 |
| solarbird | that is very strange o.O | 07:28 |
| Hyuri | is* | 07:28 |
| Hyuri | really | 07:28 |
| Hyuri | i was installing ubuntu studio to show the man that we can have a better and faster desktop to work with | 07:29 |
| cub | I guess they are not convinced now? ;) | 07:29 |
| solarbird | heh | 07:29 |
| Hyuri | eh... probably won't. he doesn't know yet | 07:30 |
| Hyuri | now is 4:30 AM here | 07:30 |
| Hyuri | i am from Brazil | 07:31 |
| Hyuri | BTW, sorry for my English. If you can correct me, please | 07:31 |
| Hyuri | appreciated | 07:31 |
| cub | Hyuri, your English is great. Not everyone here speaks English as a first language. Myself I'm in Sweden. | 07:32 |
| Hyuri | oh, good | 07:33 |
| Hyuri | i want to know Sweden some day in my life, heh | 07:33 |
| solarbird | I'm in spaaaaaaaaaaaace. Okay I'm not actually in space. I'm in Seattle. #spaaaaaaaaaaaaace | 07:34 |
| Hyuri | =) | 07:34 |
| solarbird | I'm going to bed but am going to leave this connected in case somebody sees my probably description scrollback and has an idea. | 07:36 |
| solarbird | Good luck, Hyuri! ^_^ | 07:36 |
| Hyuri | thanks! | 07:38 |
| Hyuri | good sleep | 07:38 |
| Unit193 | solarbird: Could check the dpkg logs in /var/log/ see what updates you did. | 07:48 |
| xequence | solarbird: the latest kernel update increased your minimal acceptable latency? | 07:56 |
| xequence | solarbird: did you try booting into one of the older kernels to double check? | 07:57 |
| Hyuri | Unit193: many, many thanks | 07:59 |
| Unit193 | Got it? | 07:59 |
| Hyuri | it seens the data are there | 07:59 |
| Unit193 | Great! | 07:59 |
| cub | Hyuri, wohoooo! | 07:59 |
| Hyuri | \o/ | 07:59 |
| Hyuri | thanks too cub! | 07:59 |
| cub | Oh I just did what I do best, asked someone else. ;) | 08:00 |
| Hyuri | hehe | 08:00 |
| Hyuri | the chain "cub > Unit193" saved my life =) | 08:01 |
| Unit193 | Nice that you got it, have a good one. | 08:01 |
| caodepalha | hi everyone just had ubuntustudio installed. wondering where i can find good audio plugins | 08:03 |
| xequence | caodepalha: You have a bunch preinstalled | 08:03 |
| xequence | caodepalha: Start jack, with qjackctl, then ardour. Then try adding plugins to channels | 08:04 |
| caodepalha | anything similar to the waves plugins? tape simulators etc? | 08:04 |
| caodepalha | been through the ardour plugins already. they're nice. was just wondering where i can find more plugins | 08:05 |
| caodepalha | ok thanks! | 08:07 |
| Hyuri | you can try to use win vst's with festige | 08:09 |
| Hyuri | in case you really need | 08:10 |
| caodepalha | it would be good using the waves plugins i'm used to | 08:11 |
| xequence | It's possible, but think you need a special VST build of ardour, and some wine magic | 08:12 |
| xequence | you might find more answers at #kxstudio | 08:12 |
| xequence | None of the Ubuntu Studio devs use non free software, so we don't really think about supporting that a lot - for better, or worse | 08:12 |
| xequence | It would be better if those companies started supporting Linux natively | 08:13 |
| caodepalha | that would be good | 08:13 |
| Hyuri | really good | 08:13 |
| xequence | caodepalha: There's linuxdsp | 08:13 |
| caodepalha | but with festige i could used vsts on ardour? | 08:13 |
| xequence | saying that, I do actually use non free software, but only since they are native linux plugins | 08:14 |
| caodepalha | i understand | 08:14 |
| xequence | there are some vst plugins that work natively on Linux too, but I don't know much about that | 08:14 |
| xequence | not waves, I don't think | 08:14 |
| caodepalha | i still find it a bit complicated using wine and vsts and all | 08:15 |
| xequence | caodepalha: The calf plugins are pretty decent | 08:15 |
| xequence | you can do just about anything with the plugins available, just that you might need to combine them a bit more manually then on proprietary platforms | 08:16 |
| caodepalha | anything on tape similators | 08:17 |
| caodepalha | ? | 08:17 |
| Hyuri | and you always have jack as your "universal cable" to connect them | 08:17 |
| Hyuri | heh | 08:17 |
| caodepalha | i used reaper and waves plugins but i decided to go full ubuntu | 08:18 |
| caodepalha | had it on dual boot for a while then quit windows | 08:18 |
| cub | caodepalha, there is a Ardour you can compile for win VST, but they don't recommend or support themselves. I would investige what's available through the native linux world first. Otherwise I would probably run like Reaper in Wine instead. | 08:19 |
| caodepalha | is it workable? reaper and wine? | 08:21 |
| caodepalha | with latency and all | 08:21 |
| caodepalha | ? | 08:21 |
| cub | I haven't tried it, but seems on the ubuntuforums that some are happy with that solution. | 08:23 |
| cub | But I think you can find similar plugins natively, maybe not as polished GUI as VST's but will sound good once you have learned how to set them. | 08:24 |
| caodepalha | i'd like to stay with ardour now or qtractor | 08:25 |
| caodepalha | so you would say that ardour has all one would want for audio recording? | 08:27 |
| Hyuri | TestDisk is "testing the disk". I'll go to bed now | 08:37 |
| Hyuri | many thanks for your help people | 08:37 |
| Hyuri | Unit193, cub: again, many thanks | 08:38 |
| cub | Hyuri, np glad we could help! | 08:38 |
| Unit193 | Sure, and if it can't get the partition table, hope it or photorec get the files. | 08:38 |
| cub | caodepalha, it depends on what you create in Ardour. For me there's more than enough, but I'm quite minimalistic and prefer to do as much processing and analog sound before I record | 08:39 |
| Hyuri | will try every possible step now that i have the direction | 08:39 |
| Hyuri | until next time! | 08:39 |
| caodepalha | i record acoustic guitars with condenser mics, vocals, midi keyboards | 08:40 |
| cub | caodepalha, cool. Do you have anything up on the web already? | 09:09 |
| caodepalha | yes | 09:10 |
| caodepalha | already did some recording with ardour | 09:10 |
| caodepalha | i can share if you'd like to listen | 09:10 |
| cub | caodepalha, please do | 09:11 |
| caodepalha | should i share it here'0 | 09:14 |

| simplex | hi, i have a problem booting ubuntu studio with lilo. what should i put in the lilo.conf to get it work? | 09:24 |
| cub | caodepalha, sure, as the topic says " General music making and studio chatter is allowed" and it's always fun to hear what the US community creates | 09:24 |
| xequence | simplex: lilo is no the default boot loader for Ubuntu Studio. I check Lilo docs or find a forum that deals with lilo | 09:25 |
| xequence | Sorry, missing some letters there | 09:25 |
| caodepalha | us? | 09:26 |
| xequence | Ubuntu Studio | 09:27 |
| caodepalha | ah lol | 09:28 |
| caodepalha | did u check it cub? | 09:29 |
| caodepalha | i think you where helping me the other day | 09:29 |
| caodepalha | got it all fixed by the way | 09:29 |
| cub | caodepalha, listening now. Is it the room sounding or did you add reverb in Ardour? | 09:39 |
| caodepalha | room sounding | 09:42 |
| caodepalha | hall of my house | 09:42 |
| cub | Nice! | 09:42 |
| caodepalha | recordeid live with 2 mics | 09:43 |
| caodepalha | a condenser for the guitar and a shure sm58 for the vocals | 09:43 |
| caodepalha | recorded* | 09:44 |
| cub | SM58 is great | 09:46 |
| caodepalha | i feel for my condenser mic as well | 09:47 |
| caodepalha | its large diagphragm | 09:48 |
| cub | My main maics are TSM MT87 MKII and SM58. Then again, I'm doing home recordings only. :P | 09:50 |
| caodepalha | me too for the time being | 09:54 |
| caodepalha | on my soundcloud i also have studio recordings | 09:54 |
| caodepalha | but on a different style | 09:54 |
| caodepalha | a rock band | 09:54 |
| caodepalha | by the way | 09:57 |
| caodepalha | ran into a new issue here | 09:57 |
| caodepalha | my jack wont start | 09:57 |
| caodepalha | i get this message: | 09:58 |
| caodepalha | ATTENTION: The playback device "hw:0" is already in use. The following applications are using your soundcard(s) so you should check them and stop them as necessary before trying to start JACK again: | 09:58 |
| caodepalha | pulseaudio (process ID 2156) | 09:58 |
| caodepalha | cannot load driver module alsa | 09:58 |
| caodepalha | any help? | 09:58 |
| cub | are you running any other app? | 09:58 |
| cub | since pulseaudio is occupying the hardware | 09:58 |
| caodepalha | let me check | 09:59 |
| caodepalha | no.. not as far as i can tell | 09:59 |
| caodepalha | i just installed mixbus | 09:59 |
| caodepalha | harrison | 09:59 |
| cub | I have to dash out to get lunch, sry. | 10:01 |
| caodepalha | ok its working now somehow... | 10:01 |
| caodepalha | thnks | 10:01 |
| caodepalha | hello! i just installed harrison mixbus but jack does not start with it. gives me an error. anyone knows anything about this? | 16:19 |
| caodepalha | when i start ardour or mixbus i get a: audio value for dither is missing data | 16:21 |
| solarbird | herr0 | 17:35 |
| holstein | o/ | 17:36 |
| solarbird | to answer an earlier question: the upgrade set did not appear to include a kernel upgrade and iirc I was already running .49 in the lowlatency kernel. | 17:36 |
| holstein | solarbird: i wouldnt expect those lowlatency kernel updates to "pour in" like the main ones | 17:37 |
| solarbird | going back to the generic .39 kernel improves the situation (69.7ms latency is attainable) but that's still much poorer than I should have. | 17:37 |
| holstein | solarbird: there is not "should" | 17:37 |
| holstein | solarbird: what should happen is, the manufacturer of your hardware communicates with the software developers | 17:38 |
| holstein | but, that likey is not going to happen.. so you have to do what is "best" for you | 17:38 |
| holstein | maybe that involves running a custom realtime kernel, or one from PPA for lower latency | 17:38 |
| solarbird | before those security patches from 10 days ago, I _could_ and _did_ run 28ms latency. | 17:38 |
| holstein | for my personal needs, i run different presets with differeent latency settings | 17:39 |
| holstein | for when i need/want realtime, i need under 12ms | 17:39 |
| solarbird | right, which is why i have to use hardware with hardware monitoring, becuase i've _never_ been able to get that, which I've ascribed to being on USB. | 17:40 |
| holstein | if i cant get under 12ms, then its not a scenario where i can do what i need to do, so i dont use that hardware/software scenario for realtime | 17:40 |
| holstein | solarbird: mgith be USB.. might not | 17:40 |
| holstein | solarbird: i can get around 2ms with different hardware.. depends | 17:40 |
| holstein | but, when im mixing, i typically have it set and 90+ ms.. | 17:40 |
| holstein | and, im not offereing anything as an excuse.. these are just facts | 17:41 |
| holstein | did the lowlatency kernel updates break something? if you have tested other kernels, and specifically, an older lowlatency kernel, then i think it is safe to say that, for your hardware setup, that is the case.. or appears to be | 17:41 |
| OvenWerks | solarbird: you can still boot with the older kernel, does that improve things? | 17:42 |
| solarbird | which, like I said, I can live with 70ms for mixing (268ms with the lowlatency kernel was driving me batshit even in mixing because it made finding note fragments annoying. | 17:42 |
| solarbird | .49 is the only lowlatency kernel I have installed; it did not get updated with the rest of the updates 10 days ago. | 17:42 |
| solarbird | i have a .39 _generic_ kernel which now performs better than the .49 lowlatency. | 17:43 |
| solarbird | before the updates, the .39 generic did _not_ perform better than .49 lowlatency; i moved to lowlatency as part of an attempt to improve realtime performance. | 17:43 |
| holstein | solarbird: sure.. but you would need to test an older lowlatency kernel to prove, theoretically "the updates to my lowlatncy kernel broke something" | 17:43 |
| OvenWerks | So you are not running ubuntustudio then? | 17:43 |
| solarbird | i am running ubuntustudio. | 17:43 |
| solarbird | 12.04 lts. | 17:43 |
| OvenWerks | Ubuntustudio comes with lowlatency not generic, where did the generic come from? | 17:44 |
| holstein | if lower latency were something i needed, mission critically, i would be using, as i said, a custom rt kernel. or one from ppa | 17:44 |
| solarbird | i moved to the generic tree back in... 2010?ish? and kept it updated, because some usb hardware I have responds incorrectly to probing and would hang the system with the default ubuntu-included kernel, but the newer generic available (3....1.5 maybe?) didn't, which let me use the hardware. | 17:46 |
| OvenWerks | so then this is not a 12.04 install? But an update to 12.04? | 17:47 |
| solarbird | it was not a from-scratch 12.04 lts, no. | 17:47 |
| solarbird | i can't even install 12.04lts from scratch on this hardware, the installer doesn't like my video card combination for some reason and goes to blackscreen. | 17:48 |
| OvenWerks | There are a huge number of changes from 11.04 to 11.10. I personally would not upgrade to 12.04 | 17:48 |
| OvenWerks | That would be a problem all right | 17:49 |
| holstein | solarbird: if you can run 12.04, you can run 12.04 | 17:49 |
| holstein | !nomodeset | 17:49 |
| ubottu | A common kernel (boot)parameter is nomodeset, which is needed for some graphic cards that otherwise boot into a black screen or show corrupted splash screen. See http://ubuntuforums.org/showthread.php?t=1613132 on how to use this parameter | 17:49 |
| holstein | ^^ likely need that til you get whatever driver you need installed | 17:49 |
| solarbird | yeah even the upgrade was a nightmare. i had made an image and was trying to upgrade the image, and the first three tries bricked the machine. server-upgrade command line upgrade did work tho'. | 17:50 |
| OvenWerks | Have you tried any of the live disks since 12.04? You may have to go non-LTS. | 17:50 |
| solarbird | OvenWerks: all of them go to blackscreen. well, that I tried. | 17:50 |
| OvenWerks | Also it is possible to do a studio install from the mini.iso which is all CL | 17:51 |
| holstein | solarbird: nomodeset is what is used for "going to blackscreen" | 17:51 |
| holstein | solarbird: if 12.04 works, it works.. and its able to work | 17:51 |
| holstein | solarbird: you can do *many* things to install it and get it to work | 17:51 |
| solarbird | right, but I'm already on 12.04 LTS so I don't need to worry about that now. i've been on 12.04LTS for months. | 17:53 |
| solarbird | and I did get it to work, just through the command line with server-upgrade. | 17:53 |
| OvenWerks | ok | 17:53 |
| holstein | solarbird: but, you are having "odd" issues, and its an upgrade | 17:53 |
| holstein | and that system/hard drive *will* fail | 17:53 |
| solarbird | (funny part is, there's no special drivers here. I picked the second card when I added it specifically because it had in-kernel driver.) | 17:54 |
| solarbird | sure, but i make disk image backups with dd. | 17:54 |
| holstein | solarbird: then you were using a bad iso, or something else | 17:54 |
| OvenWerks | I am surprised about the latency though. I was able to use my USB1.1 audio IF at -p64 | 17:54 |
| solarbird | holstein: I thought of that but the discs - I made more than one trying to see if that was a failure point - all passed verification | 17:55 |
| OvenWerks | (2.7ms) without issue | 17:55 |
| solarbird | OvenWerks: I know! Other people say the same thing. I've never been able. idk why. | 17:56 |
| holstein | solarbird: sorry, but you *can* use 12.04.. and it is being used.. so you *can* get an iso to support an installation | 17:56 |
| OvenWerks | With the upgrade it may be that some of the settings are not being set. I also found I had to be very careful which USB port I used. | 17:57 |
| solarbird | OvenWerks: even when I was running (a few years ago) a fresh install against my M-Audio USB FastTrack Pro (a 1.1 device) I couldn't get that. | 17:58 |
| OvenWerks | stock swappiness is 60 or 80, we set 10. that made a difference. Make sure jackd is actually able to use rt. | 17:58 |
| solarbird | Yeah, I mapped out all my USB ports for shared interrupts, trying to chase that down, with some improvement. But nowhere near 2.7ms. | 17:58 |
| solarbird | Currently I'm running against a PCI Express USB pure root device card. I was hoping that would improve things, and it did! Until 10 days ago. But even _before_ 10 days ago, I couldn't run 2.7ms even against USB 2.0 hardware. | 17:59 |
| OvenWerks | check the name of /etc/security/limits.d/audio.conf | 17:59 |
| solarbird | swappiness? | 18:00 |
| OvenWerks | make sure you are in the audio group. Those are the things >I can think of right off | 18:00 |
| solarbird | (oh for the record: top says I'm not swapping. BUT if there is a parametre I should have involving that, I don't have it in that file. I have rtprio 99 and memlock unlimited. | 18:00 |
| OvenWerks | Ya, if swappiness is set to 80, then the kernel will start putting stuuf in swap at only 20% ram in use | 18:01 |
| OvenWerks | no it would be in a different file | 18:01 |
| solarbird | oh in sysctl.conf ok | 18:04 |
| OvenWerks | You found it faster than me :) | 18:04 |
| solarbird | since we aren't swapping afaict then I'll be confused if that changes anything but it's good to know. ^_^ | 18:06 |
| OvenWerks | if it is already set to 10 that is not a problem | 18:08 |
| solarbird | it wasn't, it was at system default. | 18:08 |
| solarbird | (which is 60) | 18:08 |
| solarbird | (and I checked to make sure, it really was) | 18:08 |
| OvenWerks | I have also found that turning hyperthreading off helps lowlatency | 18:08 |
| OvenWerks | but only if I am going below 2.5ms (which I can do with an internal audio acrd in a pci slot | 18:09 |
| OvenWerks | *card | 18:09 |
| OvenWerks | It would depend on how much memory you have I was testing on a netbook with only 1g ram | 18:10 |
| OvenWerks | 40% use showed up pretty quick | 18:10 |
| OvenWerks | The issue I had was that qjackctl would get swapped out and cause lots of xruns | 18:11 |
| OvenWerks | (or maybe qjackctl's gui) | 18:12 |
| solarbird | this is a tower with 4G. it lives in a closet and never goes anywhere. I'm currently sitting at my studio desk which is close enough to the closet that long cables (single cables, no extensions... um... except on the trackball) reach it. | 18:12 |
| OvenWerks | I tried with swap off, but on an OOM error killed the session and you loose whatever you are doing. swap at least allows a retake or saving the work you have done :) | 18:13 |
| solarbird | here's my home studio in fact: http://www.youtube.com/watch?v=GziwIN5xEYk | 18:14 |
| solarbird | the two-headed monitor setup on my desk is where I am right now. :D | 18:14 |
| solarbird | right now everybody is dumping 4:3 monitors so you can get them for like $5 | 18:16 |
| solarbird | it is awesome | 18:16 |
| solarbird | if you are on a continually severe budget anyway | 18:16 |
| solarbird | i run mixer on one screen and editor on the other :D | 18:16 |
| solarbird | (it's in xinema mode) | 18:16 |
| OvenWerks | I would love to get another monitor, but I can't just now. One of my kids costs a lot to feed due to special diet. | 18:18 |
| OvenWerks | I have one of the drun pad sets too. However I don't have my own room. It has to be shared (as does the computer) with the rest of the family. | 18:19 |
| * solarbird pokes around hyperthreading commentary | 18:19 | |
| solarbird | this looks like something that would'be be a problem on a modern processor | 18:20 |
| OvenWerks | the place to find out about really lowlatency/RT work is in the computer controled milling comunity as they need sub 1ms latency | 18:20 |
| solarbird | _really_. i know a guy who does that. | 18:20 |
| solarbird | oh this is my latest song btw - i did it for a Pacific Rim convention last weekend: http://crimeandtheforcesofevil.com/blog/2013/08/the-t-rex-has-the-f-14/ | 18:21 |
| solarbird | (Probably makes more sense if you know about kaiju films) | 18:22 |
| solarbird | (no definitely makes more sense if you know about kaiju films XD ) | 18:22 |
| OvenWerks | The problem (even with modern HW) is that there are so many things that the cpu can be called to do that the OS has no comtrol over | 18:22 |
| OvenWerks | Some of the AMD chipsets with video included are really bad. | 18:22 |
| OvenWerks | The video portion takes over the cpu and busses all the time. | 18:23 |
| OvenWerks | It is interesting that some of the lower powered MB actually have better latency control | 18:24 |
| solarbird | hm, interesting | 18:29 |
| solarbird | okay yeah if i want to disable hyperthreading i appear to need to do it in BIOS | 18:30 |
| solarbird | the sample howto I found gets a LOL NO even as root XD | 18:30 |
| solarbird | brb | 18:31 |
| solarbird | yeah on my system I can't disable HT without disabling a bunch of other advanced features and the result is... not good. (at least, as far as BIOS is concerned, and trying HT only the example way fails so maybe that's consistent.) Thanks for the idea, though! It was worth a try. ^_^ | 18:47 |
| OvenWerks | Ya, the other way is to disable every second processor on the kernel command line. for example if you have two cores, dissable one and three. | 18:49 |
| OvenWerks | But like I said, I have seen no difference till I go really low latency. | 18:49 |
| OvenWerks | lower than USB for sure. | 18:49 |
| * solarbird nods | 18:50 | |
| solarbird | still, if nothing else, going back to generic kernel makes mixing okay again. plus I use live monitoring, so. | 18:54 |
| solarbird | (hardware monitoring, so latency there is irrelevant.) | 18:55 |
| OvenWerks | So long as you can make it work. I record at low latency, but mix with higher latency. | 18:57 |
| OvenWerks | I record with no effects and only playback the tracks I need. | 18:58 |
| OvenWerks | I add effects only in mixdown | 18:58 |
| OvenWerks | Some people can't work that way but I have an old P4 single core machine. | 18:58 |
| solarbird | I can pile on all the effects I want, that doesn't seem to affect things. | 18:59 |
| solarbird | whatever it is, it's not raw CPU availability. | 18:59 |
| OvenWerks | normally not. | 18:59 |
| xequence | solarbird: linux-lowlatency is updated in the same frequency as linux-generic | 19:29 |
| xequence | solarbird: linux-lowlatency is more or less a linux-generic, with a couple of changed configs | 19:30 |
| xequence | I'm the maintainer of linux-lowlatency. It's updated every three weeks in general, in cadence with linux-generic | 19:30 |
| xequence | -generic can by no means outperform -lowlatency | 19:31 |
| xequence | -lowlatency is not a realtime kernel, but provides good enough performance to get acceptable latencies with certain hardware | 19:32 |
| xequence | if you have a problem, it might be interesting to know what it is | 19:32 |
| solarbird | moving to the low-latency kernel improved things at first | 19:42 |
| solarbird | but right now -generic is _absolutely, measurably, strongly_ out-performing -lowlatency on my machine. | 19:42 |
| solarbird | and that inversion happened with the security updates I downloaded 10 ... er, now 11, I guess... days ago. | 19:43 |
| solarbird | I'd love to get back to the performance I had before that update and will provide anything you ask for. | 19:43 |
| solarbird | wait let me think. no, it was Tuesday, I think. So 10 days. | 19:45 |
| solarbird | I run apt-get update/apt-get upgrade about once a week against the 12.04 LTS tree. | 19:45 |
| xequence | solarbird: Did you check to make sure both kernels are the same verwsion | 19:50 |
| xequence | version* | 19:50 |
| solarbird | Oh, they absolutely aren't - I've been posting the version numbers. Generic is -39, lowlatency is -49. I was running lowlatency -49 before the upgrade which damaged things, and -49 after, so I haven't actually been thinking it's the kernel. | 19:52 |
| solarbird | My hypothesis is that it's something that's atomic in both that completes faster under -generic than under -lowlatency. | 19:53 |
| solarbird | But that's just a guess. It would explain the behaviour? But so could many other things. | 19:54 |
| solarbird | (The closest I came to any kernel dev work ever was writing a couple of device drivers, and a file system... well, kind of a file system and a half, since the "half" was extremely feature-limited.) | 19:58 |
| xequence | solarbird: not sure what you believe to be the version | 19:59 |
| xequence | the last digit is the upload number, so not related to version | 19:59 |
| xequence | the latest version is 3.2.0.51 | 19:59 |
| solarbird | vmlinuz-3.2.0-39-generic and vmlinuz-3.2.0-49-lowlatency | 19:59 |
| xequence | from both security and updates repos | 19:59 |
| xequence | consider that linux-lowlatency and linux-generic is the same kernel | 20:00 |
| xequence | so, if an update caused you worse performance, it might not have anything to do with the kernel being -lowlatency | 20:00 |
| xequence | solarbird: would be nice if you could install the latest -generic and try that | 20:00 |
| solarbird | so that'd be vmlinuz-3.2.0-51-generic I presume? | 20:02 |
| xequence | solarbird: do sudo apt-get update, then install both linux-lowlatency and -generic | 20:03 |
| xequence | you can do: sudo apt-get update --only-upgrade linux-lowlatency | 20:03 |
| xequence | and the same for generic | 20:03 |
| xequence | unless you have -pae | 20:04 |
| xequence | sorry | 20:04 |
| xequence | sudo apt-get install --only-upgrade linux-lowlatency | 20:04 |
| xequence | solarbird: so, both -lowlatency and -generic are now at version 3.2.0.51.61 | 20:05 |
| xequence | sorry, 3.2.0.51 | 20:05 |
| xequence | .61 previously was the upload number that I was talking about | 20:05 |
| solarbird | it's probably going to h8 on my boog.cfg but I can fix it... | 20:06 |
| solarbird | updating lowlatency... then i'll do generic... | 20:07 |
| solarbird | er, my menu.lst. lololol, ooooooooooooooold | 20:10 |
| solarbird | ha, 3-way merge worked. that doesn't usually happen. awesome. | 20:11 |
| solarbird | bringing down -51-generic... | 20:11 |
| solarbird | hoday! this will require a couple of reboots for testing | 20:16 |
| solarbird | bbiab | 20:16 |
| solarbird | okay, so both installed, and a set of basic standard tests performed. Behaviour of these is identical within margins of error of non-automated testing. | 20:49 |
| solarbird | in both cases i can get down to 46.4ms latency (which is much worse than people I've talked to with comparable hardware, but that's another issue) and 40.6 starts triggering XRUNs in Jack. | 20:50 |
| solarbird | Before 10 days ago, I could get down to around 34ms. Somehow apparently people get down to 4ms? But I've never got close to that. I got down to 17ms back in the... 08.10 days, I think? With USB 1.1 hardware. But that was just a two-channel device. | 20:52 |
| solarbird | But same-version against same-version it's definitely about the same. | 20:53 |
| solarbird | I'm wondering if something was fucked up in my 3.2.0-49 low-latency install - it was through the package manager, but who knows. | 20:55 |
| xequence | solarbird: Would seem to me your hardware is the problem here | 21:02 |
| xequence | solarbird: I get under 10ms without problems, but I don't have usb | 21:03 |
| xequence | pci and firewire | 21:03 |
| xequence | I haven't tried the latest 3.2 kernels though | 21:03 |
| solarbird | Yeah, USB is kinda suck. But other USB users have better performance I do, it's... been a thing. I'd love to move off USB tho'. Next time I have money, ne? XD | 21:04 |
| solarbird | For live I have hardware monitoring, so as long as it's under, idk, 65ms or so? I can cope with it in mixing. | 21:05 |
| xequence | If you only do mixing, you don't really require low latency at all | 21:06 |
| xequence | I can't live with anything over 15ms for live audio processing | 21:06 |
| solarbird | Yeah, which is why I can only use (so far, anyway) hardware that supports hardware monitoring. | 21:08 |
| solarbird | I'd _like_ to throw $N00 or $N000 at some monster PCI-attached device, but that requires $N00 or $N000... | 21:09 |
| solarbird | hardware monitoring requires that you not need to mix in effects at the time tho'. which is a limitation that so far I've just lived with. | 21:10 |
| solarbird | I mean originally I built this little studio just for my own use, but now I've got other bands who want to use it (and hire me as their engineer :D ) so I'm caring more about that sort of thing. | 21:11 |
| solarbird | (I'd point at one of them but despite the fact that one in particular's album IS in fact OUT, certain bands don't have it on Bandcamp yet, so I can't...) | 21:13 |
| xequence | solarbird: I have m-audio delta 1010 and 66. Same chip on all delta devices. Works great | 21:15 |
| xequence | also, focusrite sapphire pro 40 | 21:15 |
| xequence | solarbird: We haven't got a lot written down about usb devices, but here's a clue if you want to try that some more https://help.ubuntu.com/community/UbuntuStudio/SupportedHardware#USB | 21:16 |
| cub | When I was going to buy a usb card 3 years back I read tons of threads on the ubuntuforums and then it seemed the Edirol UA-25EX was a popular one working of the bat. | 21:18 |
| solarbird | oh that sapphire pro40 looks soooo tasty | 21:19 |
| solarbird | oh i'm not wedded to USB. I'm on USB because the interfaces I could get for the dollars I've had have been USB. | 21:21 |
| solarbird | like, this tascam us-800 i'm using, I picked it up on clearance, new,] for $80. | 21:23 |
| * solarbird adds Sapphire Pro 40 to wishlist | 21:24 | |
| solarbird | YOU NEVER KNOW :D | 21:25 |
| cub | Hi Hyuri how did it go with the partition? | 21:31 |
| Hyuri | bad =( | 21:31 |
| cub | oh | 21:31 |
| Hyuri | no results | 21:31 |
| solarbird | "oh :( | 21:32 |
| Hyuri | in ubuntu studio shows as free space | 21:32 |
| Hyuri | i will try TestDisk again | 21:33 |
| cub | how's your friend taking it? | 21:33 |
| Hyuri | Fortunately, he said he would come today but did not come | 21:34 |
| Hyuri | 1 more day to try solving it | 21:35 |
| cub | like an episode of 24... | 21:35 |
| cub | wait, no a season. anyhow. | 21:35 |
| Hyuri | hehe | 21:36 |
| cub | I haven't used TestDisk, but I thought it would try to recover the partition? | 21:36 |
| cub | but ubuntu studio still show it as free space, so no change from before? | 21:36 |
| Hyuri | no change | 21:37 |
| cub | Unit193, ^ any ideas? | 21:37 |
| cub | but, there was two HDD, one partition on each? Where did Ubuntu studio install itself? | 21:38 |
| Hyuri | 2 partitions, 1 with 1TB, 1 with 80GB. Ubuntu Studio installed itself on the 1TB | 21:39 |
| Hyuri | 80GB partition is intact | 21:40 |
| Hyuri | 2 HDDs i mean | 21:40 |
| cub | or perhaps xequence ? Hyuri was to install US alongside windows, but there was two windows installation and the *important* one disappeared. | 21:41 |
| Hyuri | 1 partition on each. exatcly | 21:41 |
| cub | so Ubuntu Studio did overwrite the 1TB where the important windows was installed? | 21:41 |
| Hyuri | yes | 21:42 |
| Hyuri | now i am on the windows of the 80GB HDD, to manage the other HDD, wich now has only US | 21:42 |
| cub | I'd like to help, but it's late here and I need to get up early to drive the family tomorrow. :/ | 21:43 |
| Hyuri | no problems | 21:44 |
| cub | I have pinged a couple of people, hopefully they might be able to help out. | 21:44 |
| Hyuri | =) | 21:44 |
| Hyuri | thank you | 21:44 |
| Hyuri | MS Data on TestDisk is related to windows files? anyone you know? | 21:44 |
| cub | good luck Hyuri, I hope to read good news in the channel log tomorrow. ;) | 21:45 |
| Unit193 | If the files were overwritten, then you won't really be able to get the files. | 22:15 |
| Hyuri | =º | 22:20 |
| Hyuri | i think US is taking about 8GB | 22:21 |
| Hyuri | if at least i could save the files, are ok | 22:24 |
| Unit193 | When it was scanning for partitions, there is an option to "view" them. | 22:26 |
| Hyuri | on TestDisk? | 22:29 |
| Unit193 | Aye. | 22:29 |
| Hyuri | didn't saw it | 22:33 |
| Hyuri | indeed, i got confused in one part | 22:33 |
| Hyuri | the article shows a situation that is not compatible wich waht i am getting | 22:34 |
| Hyuri | after [Quick Search], TestDisk shows a list with "1 P Unknown", "2 P MS Data" and "3 P Linux Swap". Do you know what that means? | 22:36 |
| Hyuri | not after, before*. Sorry | 22:36 |
| Hyuri | before pressing [Quick Search] i have this list | 22:36 |
| Unit193 | Current partition structure | 22:37 |
| Hyuri | so the windows are being recognized? MS Data is windows data, right? | 22:38 |
| Unit193 | You'd think it'd say the linux/ext4 one too. | 22:40 |
| Hyuri | didn't got it | 22:45 |
