| georgeowell | Just installing 15.10 on my laptop | 01:31 |
|---|---|---|
| georgeowell | Want to dual boot with the Windows malware | 01:32 |
| georgeowell | So tense... | 01:32 |
| georgeowell | hehe worked like a charm | 01:39 |
| georgeowell | Will the GNOME3 desktop work on top of all the ubuntu studio stuff | 02:44 |
| OvenWerks | georgeowell: no reason that I know for it not to so long as you are using ubuntu packages. Can't say as I have been there myself though. | 02:53 |
| georgeowell | Maybe I'll leave that experiment for another time. | 02:56 |
| georgeowell | Somethings happened with my Jack setup already | 02:57 |
| georgeowell | I'm getting D-BUS: Jack Server could not be started | 02:58 |
| OvenWerks | I think we need a better jack tool... I would like a better jack package as well. having both jackd and jackdbus on the same system does have some uses, but seems to cause more trouble than it is worth. | 02:58 |
| georgeowell | is there a way of returning to the default config? | 02:58 |
| OvenWerks | how do you start jack? qjackctl? | 02:58 |
| georgeowell | yep | 02:59 |
| georgeowell | The only parameter I changed was Frames/Period | 02:59 |
| OvenWerks | in a terminal try killall -9 jackd jackdbus. | 02:59 |
| OvenWerks | default is 1024/2 | 02:59 |
| OvenWerks | then restart jackdbus using qjackctl | 03:00 |
| georgeowell | OvenWerks, I got "no process found" | 03:00 |
| OvenWerks | sometimes if jack is not running a jack application will start jackd which blocks jackdbus from starting | 03:00 |
| OvenWerks | that is ok I think. | 03:01 |
| OvenWerks | what happens if you try jack_control start? | 03:01 |
| leo_ | hey sorry just jumped into IRC on Ubuntu Studio box | 03:03 |
| OvenWerks | hello | 03:03 |
| leo_ | OvenWerks, I'm getting: | 03:04 |
| leo_ | DBus exception: org.jackaudio.Error.Generic: Failed to open server | 03:04 |
| leo_ | I rebooted as well | 03:04 |
| OvenWerks | Does this mean you are the same person as georgeowell ? | 03:04 |
| leo_ | yep | 03:04 |
| OvenWerks | ah. | 03:04 |
| leo_ | sorry, asif I needed the make the situation any more complicated :) | 03:05 |
| OvenWerks | But it was working before? | 03:05 |
| OvenWerks | leo_: try this in a terminal: | 03:06 |
| OvenWerks | cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh | 03:06 |
| leo_ | yep perfectly | 03:06 |
| OvenWerks | paste the output to pastebin.com or similar | 03:06 |
| leo_ | Would it help if I showed you the errors direct from qjackctl messages? | 03:08 |
| OvenWerks | The above command will tell more I think. | 03:08 |
| leo_ | there's the qjackctl stuff | 03:09 |
| leo_ | http://pastebin.com/Xj7nPhQE | 03:09 |
| leo_ | and the result of the jackaudio script | 03:10 |
| leo_ | http://pastebin.com/Dzm2JFsT | 03:10 |
| OvenWerks | leo_: That just says something else is using it. | 03:10 |
| leo_ | So something is starting jack automatically? | 03:11 |
| OvenWerks | leo_: or that you have specified a device that does not exist. | 03:12 |
| leo_ | OvenWerks, thanks so much for this btw. I only just installed so this is super frustrating. | 03:12 |
| OvenWerks | The second one shows nothing is using a device | 03:12 |
| OvenWerks | which device are you trying to connect to? | 03:12 |
| leo_ | ok wtf, it just started working again. Sorry 2 secs, let me just test. | 03:13 |
| OvenWerks | The second paste should have had a lot more info. | 03:13 |
| * OvenWerks has not run that with no jackdbus running though | 03:15 | |
| OvenWerks | leo_: I think hw:MID is the device you want to use. | 03:16 |
| leo_ | Yep, that's the right device. | 03:17 |
| leo_ | I just don't understand why it got all messed up | 03:17 |
| leo_ | I thought it was working for a second but now I'm in the same situation as when I began | 03:18 |
| OvenWerks | ok lets try jack_control exit | 03:21 |
| leo_ | tried that already | 03:22 |
| OvenWerks | jack_control ds alsa dps capture none dps playback none | 03:22 |
| leo_ | This is what I get on jack_control start: DBus exception: org.jackaudio.Error.Generic: Failed to open server | 03:22 |
| OvenWerks | jack_control jack_control dps device hw:MID dps rate 48000 dps period 1024 dps nperiods 2 start | 03:23 |
| OvenWerks | ok killall -9 jackdbus jackd | 03:23 |
| leo_ | same error | 03:23 |
| OvenWerks | then three commands above in the same order. | 03:23 |
| leo_ | ok, it appears to be working | 03:25 |
| leo_ | shall I try qjackctl | 03:25 |
| leo_ | ? | 03:25 |
| OvenWerks | qjackctl should show jack as already running | 03:26 |
| OvenWerks | (go ahead) | 03:26 |
| leo_ | hehe | 03:26 |
| leo_ | its working | 03:26 |
| leo_ | thanks so much!! :) | 03:26 |
| * leo_ hugs OvenWerks in glee | 03:27 | |
| OvenWerks | leo_: ok, that tells me that you probably have an odd setup in qjackctl. | 03:27 |
| leo_ | ok | 03:27 |
| leo_ | it's something to do with "frames/period" | 03:28 |
| leo_ | it is now 4096 | 03:28 |
| OvenWerks | leo_: did you change name from (default)? | 03:28 |
| leo_ | nope | 03:28 |
| OvenWerks | 4096 may be to high for your card | 03:28 |
| OvenWerks | it is too high for my multi track card. | 03:29 |
| leo_ | I changed it from 4096 and then the problem started | 03:29 |
| OvenWerks | try 1024 (which is what we used from command line) | 03:29 |
| leo_ | It works on 4096 | 03:29 |
| leo_ | is that the buffer size? | 03:30 |
| OvenWerks | It work on 1024, because that is how we started it from the command line | 03:30 |
| leo_ | ok | 03:30 |
| leo_ | I'll change it in qjack and see what happens | 03:30 |
| OvenWerks | it is part of the buffer size. | 03:30 |
| OvenWerks | buffer size is frames times periods | 03:31 |
| OvenWerks | 1024/2 is normally the highest anyone goes | 03:32 |
| leo_ | yep | 03:32 |
| leo_ | It's working | 03:32 |
| OvenWerks | there will be a noticable delay between audio going in to audio coming out | 03:32 |
| leo_ | yep | 03:32 |
| OvenWerks | (43 ms) | 03:32 |
| leo_ | Is it possible to go lower with intel audio without xruns? | 03:33 |
| OvenWerks | 64/2 is very good, but I find internal audio can normally not get below 128/2 | 03:33 |
| leo_ | I still need to get a linux compatible interface | 03:33 |
| OvenWerks | no xruns depends on a lot of things :) | 03:33 |
| leo_ | i'll try 256 | 03:33 |
| leo_ | hehe my bastion of fire into the linux audio world!! | 03:34 |
| OvenWerks | On my lap top I found I had to unload the wifi driver. | 03:34 |
| leo_ | ah yes, even disabling the wifi on my mac helps latency | 03:34 |
| leo_ | 256 is fine for me right now | 03:35 |
| OvenWerks | 256/2 is not too bad, 512 sounds echoy if you are monitoring from the soundcard. Recording with 1024/2 with external monitoring is fine though. | 03:36 |
| leo_ | I'm going to get one of those focusrite scarlett interfaces | 03:36 |
| leo_ | then see how far I can push it | 03:36 |
| OvenWerks | with USB try each USB plug on the computer. Some of them with share interupts with other things. | 03:36 |
| OvenWerks | you want a clean interupt for lowest latency | 03:37 |
| leo_ | I'm not actually using this linux setup for recording yet, just for playing around with all the cool free software stuff | 03:37 |
| leo_ | I'm on a thinkpad so there's many to try | 03:37 |
| leo_ | What audio interface are you using? | 03:37 |
| OvenWerks | I am using an old Maudio delta66 PCI card. | 03:38 |
| OvenWerks | I can get .7ms latency with it. (16/2) | 03:38 |
| OvenWerks | (plus 1ms each way for the ADC/DAC) | 03:39 |
| leo_ | that's pretty amazing | 03:39 |
| leo_ | on my macbook pro, I probably get 11ms. | 03:39 |
| OvenWerks | nobody makes PCI stuff anymore | 03:39 |
| OvenWerks | PCIe stuff is $1k for just about anything worth whle. | 03:40 |
| leo_ | From research, some of the Focusrite USB interfaces are working well with Linux | 03:40 |
| OvenWerks | yes or the 1818vsl (i think) | 03:41 |
| OvenWerks | https://www.presonus.com/products/AudioBox-1818VSL or it's siblings | 03:42 |
| OvenWerks | (theres a 22 and a 44 as well) | 03:43 |
| OvenWerks | I would stay away from the USB mic. You want your interface to have both the inputs and outputs you use for recording if possible. | 03:44 |
| OvenWerks | otherwise you have to use sample rate conversion to sync them. | 03:44 |
| leo_ | thanks for the advice | 03:45 |
| leo_ | I was looking at this: http://us.focusrite.com/usb-audio-interfaces/scarlett-6i6 | 03:46 |
| leo_ | I've used them before | 03:46 |
| leo_ | and can test with Linux before I buy | 03:47 |
| OvenWerks | looks good but I have never used one before. I normally take my laptop to the music store and try what I want in the store. | 03:48 |
| OvenWerks | be aware that it may not be possible to control everything in the box, so if any effects come with it you may not be able to control them. | 03:48 |
| leo_ | Yeh, a good music shop will be cool with that. | 03:49 |
| leo_ | Yeh, only need the raw ins and outs | 03:49 |
| leo_ | not bothered about their fancy routing software | 03:49 |
| OvenWerks | heres the user guide: http://d3se566zfvnmhf.cloudfront.net/sites/default/files/focusrite/downloads/9439/scarlett6i6-user-guideen.pdf | 03:50 |
| leo_ | Thanks | 03:51 |
| leo_ | You've been so helpful. What a credit to this community. | 03:52 |
| OvenWerks | not sure if MixControl would be useful from wine or not... or if you want wine on the system | 03:52 |
| leo_ | I'll send you over some of the music I make using free software :) | 03:52 |
| leo_ | I just got back from Berlin, so it's all Techno I'm afraid. | 03:52 |
| leo_ | Well anyway all credit to the Ubuntu Studio project | 03:57 |
| leo_ | didn't think I'd be having this much fun with music on Linux | 03:58 |
| OvenWerks | Almost all manufactures have the manuals on line. | 03:58 |
| OvenWerks | It seems that 6i6 stuff in Linux is quite new 15.04 and newer | 03:59 |
| leo_ | ah maybe I might need to go for a more basic model | 04:01 |
| leo_ | that has more stable support | 04:01 |
| leo_ | I wonder who is working on that specifically | 04:02 |
| leo_ | I'll love to donate a bit of cash to them | 04:02 |
| OvenWerks | I think it will be similar for any of them. | 04:02 |
| OvenWerks | The alsa project is doing that. | 04:02 |
| leo_ | It's great work | 04:04 |
| leo_ | Ardour is looking super nice these days as well | 04:05 |
| OvenWerks | anyway, I should go eat. | 04:07 |
| leo_ | Thanks so much for your help! | 04:10 |
| leo_ | I copied all the commands so I should be able to fix it myself next time | 04:11 |
| leo_ | here's a sample of what I'm working on | 04:15 |
| leo_ | http://46.101.47.165/owncloud/index.php/s/cQ2Wxr6seapw4vH | 04:16 |
| leo_ | for anyone who's interested :) | 04:16 |
