| benhem | hi, I am pretty set on embarking on an upgrade from ubuntu 10.11 to ubuntustudio 10.11 ... I'm reading this document: | 05:02 |
|---|---|---|
| benhem | https://help.ubuntu.com/community/Ubuntu%20Studio%20Upgrade%20from%20Ubuntu | 05:02 |
| benhem | it says "warning, contents under construction" -- I don't want to risk lousing this all up -- are there any specific things anyone can tell me to look out for? | 05:02 |
| benhem | thank | 05:02 |
| benhem | *thanks | 05:02 |
| holstein | benhem: i would start like this... what do you want to do? | 05:04 |
| holstein | you dont need any of the ubuntustudio stuff | 05:04 |
| holstein | you can open a pacakge manger, synaptic, or the software center and search 'ubuntustudio' | 05:04 |
| holstein | you'll see all the metapackages | 05:04 |
| holstein | there are a few that are just for the look and feel | 05:04 |
| benhem | I want a realtime kernel for midi recording, mostly, but the rest sounds pretty cool too | 05:04 |
| holstein | benhem: we dont have a kernel RT anymore | 05:05 |
| holstein | its not in debian upstream | 05:05 |
| holstein | and you dont need anything from ubuntustudio to have a kernel RT | 05:05 |
| benhem | ergh, what option does that leave me? I couldn't find a way to install a low latency, preempt, or realtime kernel on 10.11 | 05:05 |
| holstein | https://launchpad.net/~abogani/+archive/ppa | 05:05 |
| holstein | benhem: i urge you to try the generic | 05:05 |
| holstein | then the lowlatency | 05:05 |
| holstein | then the RT | 05:05 |
| benhem | well, I'm on generic now, can't figure out how I'd try the others | 05:05 |
| holstein | we are finding most dont need the RT kenrel anymore | 05:06 |
| benhem | generic stutters and drops stuff | 05:06 |
| holstein | benhem: you add that PPA i linked | 05:06 |
| benhem | *might* be a botched jack setup though | 05:06 |
| holstein | it has the kernels | 05:06 |
| holstein | benhem: you can try starting things as root *to test* | 05:06 |
| benhem | oh, ok | 05:06 |
| holstein | and see if its permission | 05:06 |
| holstein | s | 05:06 |
| holstein | benhem: we wont have, or need to have a kernel RT much longer | 05:06 |
| holstein | benhem: you can ask around in #opensourcemusicians | 05:07 |
| holstein | lots of MIDI guys there | 05:07 |
| benhem | ok, thanks | 05:07 |
| holstein | im using a realtime kernel in ubuntu 10.04 | 05:07 |
| holstein | the one from the kxstudio ppa's | 05:07 |
| holstein | benhem: also, if you are using an internal soundcard, and you are getting around 20ms latency, thats quite good | 05:08 |
| benhem | I am really confused about the latency and the jack setup | 05:09 |
| holstein | even something like this http://www.behringer.com/EN/Products/UCA202.aspx can really step things up | 05:09 |
| benhem | it says "latency, 21.3 msec" with my current settings: 128frames/period, 48000 sample rate, 8 periods/buffer | 05:09 |
| holstein | benhem: yup | 05:09 |
| benhem | but it still hiccups and drops stuff | 05:09 |
| holstein | if thats an internal sound card, thats great | 05:09 |
| holstein | you can check that 48000 is what your card likes | 05:10 |
| holstein | the frames/period and periods/buffer are what we tweak | 05:10 |
| benhem | ok, looking up stats on my sound card | 05:10 |
| holstein | you want to try 2 periods/buffer and 512 frames/period | 05:11 |
| holstein | thats a good place to start | 05:11 |
| benhem | ok | 05:11 |
| holstein | then, go to 256 frames/period | 05:11 |
| holstein | 48000 is usually OK | 05:11 |
| benhem | 512/2 leaves me with the same latency, 21.3 | 05:11 |
| benhem | trying it out | 05:11 |
| holstein | benhem: is it an internal sound card? | 05:11 |
| benhem | yep, everything is stock | 05:12 |
| benhem | just a laptop | 05:12 |
| holstein | benhem: that card i linked is like $30 us | 05:12 |
| benhem | huh, ok | 05:12 |
| holstein | you can ask around in #opensourcemusians | 05:12 |
| holstein | other folks use that card | 05:12 |
| holstein | benhem: you'll *never* get the performance you want out of that card | 05:12 |
| benhem | the internal one in my laptop? | 05:16 |
| holstein | benhem: right | 05:16 |
| benhem | hmm, my old setup with ubuntu 9 worked well | 05:16 |
| holstein | benhem: yeah? | 05:17 |
| holstein | benhem: install that then | 05:17 |
| benhem | I don't know what the key differences were | 05:17 |
| holstein | benhem: systems evolve | 05:17 |
| holstein | kernels change | 05:17 |
| benhem | I'm tempted | 05:17 |
| holstein | you dont want to use that internal card | 05:17 |
| benhem | but I was hoping that ubuntu-studio would be a sort of sideways migration that would achieve the same ends | 05:17 |
| holstein | that'll be the best 3 bucks you ever spent | 05:17 |
| benhem | (and I wouldn't have to mess with backing up my data) | 05:17 |
| benhem | ok, I'll check out the card, thanks for that | 05:17 |
| holstein | benhem: nah | 05:17 |
| holstein | ubuntustudio *is* ubuntu | 05:18 |
| holstein | benhem: you can try AVlinux live | 05:18 |
| holstein | theres a new dynebolic live CD | 05:18 |
| holstein | still.. *no* studio uses internal sound cards | 05:18 |
| holstein | also, you might not need low latency | 05:20 |
| holstein | depends on what you are doing | 05:20 |
| benhem | I'm beginning to wonder if my real problem is latency or not | 05:20 |
| holstein | i typically mix and track at like 60+ms | 05:20 |
| holstein | i have different JACK profiles | 05:20 |
| benhem | because the problem is a stutter where it drops a full half-second of input | 05:20 |
| holstein | i can do 1.2ms stable | 05:20 |
| holstein | but i rarely need to | 05:20 |
| holstein | if im playing something in live, and i want realtime effects at the time in tracking | 05:21 |
| holstein | or im using a MIDI instrument | 05:21 |
| holstein | otherwise.. who cares if when i push play, it takes 60ms to come out the speakers... | 05:21 |
| holstein | benhem: that could be a kernel driver support issue | 05:22 |
| holstein | alsa | 05:22 |
| holstein | who knows | 05:22 |
| holstein | i would try some live CD's | 05:22 |
| holstein | theres even a puppy live CD with ubuntustudio pacakges ;) | 05:22 |
| benhem | hmm, ok | 05:24 |
| holstein | of course, you should find better alsa/JACK support with that USB device i suggested | 05:25 |
| benhem | yeah. I _am_ wondering if I should just go back to karmic for the realtime kernel support | 05:25 |
| benhem | I hate Unity too :) | 05:25 |
| holstein | well, dont go for the kernel | 05:26 |
| holstein | thats over | 05:26 |
| holstein | seriously | 05:26 |
| holstein | i mean, im not planning on using unity either | 05:26 |
| holstein | but, the generic kernel is quite suitable right now | 05:26 |
| holstein | and will be ready soon | 05:26 |
| benhem | hmm, ok | 05:26 |
| holstein | theres the liquorix kernel too | 05:26 |
| holstein | i mean, try what you want | 05:26 |
| benhem | well, I appreciate the advice | 05:28 |
| benhem | I'll also try that #opensourcemusicians | 05:28 |
| holstein | yeah | 05:28 |
| holstein | lost of folks there useing ubuntu with the generic kernel doing MIDI | 05:28 |
| holstein | also, guys use RT kernels of their own with whatever distro's | 05:29 |
| benhem | I can't imagine there's a downside to trying that lowlatency kernel from the ppa you linked | 05:31 |
| benhem | if it doesn't replace my generic | 05:31 |
| holstein | benhem: nothing does anything... you can replace it though | 05:32 |
| holstein | you just add them | 05:32 |
| holstein | i go in and tell grub to unhide | 05:32 |
| holstein | !grub2 | 05:32 |
| ubottu | GRUB2 is the default Ubuntu boot manager since 9.10 (Karmic). Lost GRUB after installing Windows? See https://help.ubuntu.com/community/RestoreGrub - For more information and troubleshooting for GRUB2 please refer to https://help.ubuntu.com/community/Grub2 - See !grub1 for releases before Karmic (9.10) | 05:32 |
| holstein | you can read about how to do that there ^^ | 05:32 |
| benhem | huh, ok | 05:32 |
| holstein | you'll add the PPA, then you'll run sudo apt-get update | 05:32 |
| holstein | then you can install in... linux-lowlatency or whatever | 05:33 |
| holstein | sudo apt-get install linux-lowlatency | 05:33 |
| holstein | then, you can edit /etc/default/grub | 05:33 |
| kimal73 | hello i wont install ubuntu studio, can i do the 11.10 release from dvd? | 08:54 |
| larstr | 11.10 is indeed available on dvd | 09:01 |
| kimal73 | larstr: yes, but someone had probelms | 09:21 |
| kimal73 | *problems | 09:21 |
| kimal73 | larstr: have you the 11,10? | 09:22 |
| larstr | kimal73: yes, I'm running 11.10 | 09:38 |
| kimal73 | larstr: ok, i have xfce desktop on ubuntu 11.10. So i installed ubuntustudio desktop too. But the kerner realtime isn't on repo of synamtic. Is it the same thing? | 09:51 |
| SachinDey | I read that UbuntuStudio's new envronment is XFCE, does it has the network manager like gnome that can detect USB modems? | 11:01 |
| larstr | kimal73: RT kernel is not included anymore | 11:13 |
| ailo | kimal73, The repo for Ubuntu and Ubuntu Studio is the same. No rt kernel. Future releases should include a -lowlatency kernel however. | 11:15 |
| ailo | kimal73, The -generic kernel performs fairly well. Depending on your hardware, you might find it good enough for your needs | 11:16 |
| ailo | Also depending on your needs of course | 11:17 |
| kimal73 | ailo: ok | 11:43 |
| zx81 | hi | 12:56 |
| zx81 | i have sound problem disconnecting after 10 minutes ago ???? | 12:56 |
| zx81 | when i use Qjack ctl, or other app like skype) the sound is crunching and cut | 12:58 |
| zx81 | what is this problem ?? | 12:58 |
| ailo | zx81, Are you using Ubuntu Studio? | 13:00 |
| zx81 | yes | 13:01 |
| ailo | Do you understand what jack is and that qjackctl is an application for controlling jack? | 13:02 |
| ailo | I was wondering, since you mentioned Skype and qjackctl as two apps you were having a problem with | 13:02 |
| zx81 | yes i have using jack, | 13:02 |
| ailo | Do you connect pulseaudio to jack? | 13:02 |
| ailo | Do you know about pulseaudio? | 13:03 |
| zx81 | skype and jack never connecting with the same config | 13:03 |
| zx81 | but i have the same result | 13:04 |
| zx81 | when i use jack | 13:04 |
| zx81 | or when i use skype with pulse | 13:04 |
| zx81 | i know it is not the same way and config but it look like a memory problem ??? | 13:05 |
| zx81 | i search why ?? | 13:05 |
| ailo | I'm still not sure if you are using pulseaudio with jack or not | 13:05 |
| zx81 | no | 13:05 |
| ailo | Ok, so then it is not a problem with either jack or pulseaudio | 13:06 |
| zx81 | with jack i use alsa | 13:06 |
| zx81 | i have just change of system | 13:07 |
| zx81 | with skype its pulse | 13:07 |
| ailo | In any case it is not a problem with either jack or pulseaudio | 13:08 |
| ailo | Have you used the same computer and sound card with Ubuntu Studio in the past? | 13:09 |
| zx81 | waouu sorry i'm just trying to use jack but to day its crach | 13:09 |
| ailo | Or any other linux installation | 13:09 |
| zx81 | DBUS problem yet | 13:09 |
| ailo | Do you know hot to set realtime privilige for the user? | 13:09 |
| ailo | how* | 13:10 |
| zx81 | yes same | 13:10 |
| zx81 | no | 13:10 |
| zx81 | may be its that | 13:10 |
| ailo | If you always have a sound problem on that computer with linux, I suggest it is a hardware problem | 13:10 |
| ailo | Pulseaudio does not need realtime privilege, but jack does | 13:11 |
| zx81 | no in the past no problem | 13:11 |
| ailo | Is it only Skype that does not work, or do you have problems with all applications? | 13:11 |
| zx81 | can u help me to define the privilege?? | 13:11 |
| ailo | To give yourself realtime priority, do this in a terminal: sudo dpkg-reconfigure jackd | 13:12 |
| ailo | When you are asked if you want to use realtime or not, answer yes | 13:13 |
| ailo | After that you do this in a terminal: sudo usermod -a -G audio <username> | 13:13 |
| ailo | replace <username> with your username | 13:13 |
| zx81 | Cannot connect to server socket err = Aucun fichier ou dossier de ce type | 13:13 |
| ailo | Then reboot | 13:13 |
| ailo | Just follow those steps, and you will get realtime priority for jack | 13:14 |
| ailo | Are you comfortable using a terminal? | 13:14 |
| zx81 | all my cumputer is freezing ??? | 13:14 |
| zx81 | he windows staty open after clic close | 13:15 |
| ailo | This information is not bery helpful | 13:16 |
| ailo | very* | 13:16 |
| ailo | Pulseaudio should work without problems, except for when you use jack | 13:17 |
| ailo | jack will only work in realtime mode, if you have set the privileges | 13:17 |
| ailo | To get realtime privilege, just follow the steps I just described | 13:18 |
| zx81 | when i type sudo dpkg-reconfigure jackd | 13:18 |
| zx81 | its made nothing | 13:18 |
| ailo | try: sudo dpkg-reconfigure jackd2 | 13:19 |
| ailo | jackd2 should be installed by default, when installing jack. There's also jackd1 | 13:20 |
| ailo | If it's not one, it will be the other | 13:20 |
| zx81 | ok its ok with jackd2 | 13:21 |
| zx81 | i must reboot | 13:22 |
| zx81 | ?? | 13:22 |
| zx81 | and back after test | 13:22 |
| zx81 | tk | 13:22 |
| ailo | Yes, you have to reboot | 13:22 |
| zx81 | for help | 13:22 |
| ailo | np | 13:22 |
| zx81 | at soon for the result | 13:23 |
| zx81 | ailo | 13:26 |
| zx81 | reboot and qjack is open | 13:26 |
| ailo | zx81, Yes.. | 13:26 |
| ailo | Default settings for qjackctl should work fine | 13:27 |
| zx81 | in connexions i have PulseAudioJanckSink/ Pulse audio Jack Source | 13:27 |
| zx81 | System / System | 13:27 |
| zx81 | i have made a link in / out of sytem to ear my microphone in playback ((((( | 13:28 |
| zx81 | all look like fine | 13:28 |
| ailo | Is this a pure Ubuntu Studio installation, or did you add something to it? | 13:29 |
| zx81 | nothing | 13:29 |
| ailo | Oneiric? | 13:29 |
| zx81 | yes | 13:29 |
| ailo | ok | 13:29 |
| ailo | Sounds like you can have everything running through jack | 13:29 |
| zx81 | there is little change | 13:29 |
| zx81 | its fun | 13:29 |
| zx81 | i must try skype open | 13:29 |
| zx81 | ok great | 13:32 |
| zx81 | skype is run when i cut jack ___ Normal | 13:32 |
| zx81 | and when i open jack after skype _____ yupppp | 13:33 |
| zx81 | ailo a drink virtual to you !! | 13:33 |
| ailo | zx81, Have fun! | 13:34 |
| zx81 | what u made with jack ?? | 13:34 |
| zx81 | some music ?? | 13:34 |
| ailo | I mostly use a program called puredata | 13:35 |
| zx81 | dont know | 13:35 |
| ailo | Or rather, pd-extended, which is slightly prettier | 13:35 |
| ailo | It is a graphical audio/video programming language | 13:35 |
| zx81 | vdjing ?* | 13:36 |
| ailo | http://puredata.info/ | 13:37 |
| zx81 | im french , n u ? | 13:37 |
| ailo | Swedish/Finnish | 13:38 |
| zx81 | its fun puredata | 13:38 |
| ailo | I think so | 13:38 |
| zx81 | ok video projection | 13:38 |
| ailo | Sure, video, but also everything concerning audio | 13:38 |
| zx81 | did u know a ap for lighting dmx | 13:39 |
| ailo | Nope. I haven't done any light or graphical stuff myself | 13:39 |
| zx81 | ok | 13:39 |
| zx81 | music ? | 13:40 |
| ailo | Yea, I make music mostly. And you? | 13:40 |
| zx81 | yea | 13:40 |
| zx81 | i use just | 13:40 |
| zx81 | rec | 13:40 |
| zx81 | lol | 13:40 |
| zx81 | since linux | 13:41 |
| zx81 | rec guitar drum bass | 13:41 |
| zx81 | all instrumental | 13:41 |
| ailo | I started out playing death metal | 13:41 |
| ailo | Drums and guitar | 13:41 |
| ailo | I also play piano | 13:41 |
| ailo | Classical | 13:41 |
| zx81 | did u know a trick to connect more one sound card ?? | 13:42 |
| zx81 | me im experimental music | 13:42 |
| ailo | It is possible to connect more than one sound card, but I believe they have to be the same chip | 13:43 |
| ailo | At least for pci cards | 13:43 |
| ailo | I have connected two m-audio cards | 13:43 |
| zx81 | i search but i dont find | 13:43 |
| ailo | M-66 and LT-1010 | 13:43 |
| zx81 | i have maudio producer usb micro | 13:43 |
| ailo | usb I don't know | 13:44 |
| zx81 | and i search to connect that with a other card | 13:44 |
| zx81 | fine | 13:44 |
| zx81 | great product | 13:44 |
| zx81 | for voice or guitar | 13:45 |
| ailo | http://alsa.opensrc.org/MultipleUSBAudioDevices | 13:45 |
| ailo | The problem with usb is that you usually only get 16 bit 44kHz, because there are no dedicated drivers | 13:45 |
| ailo | Only usb 1.1 compatibility | 13:46 |
| ailo | Well, maybe 48kHz, 16bits, depending on the setup | 13:46 |
| ailo | I have almost no experience with usb | 13:47 |
| ailo | pci works well. I just bought a firewire device last year, and that works good as well | 13:47 |
| zx81 | multiple card its not easy ... | 13:47 |
| zx81 | my english ,,,, | 13:48 |
| zx81 | and all terminal config | 13:48 |
| zx81 | im not expert | 13:48 |
| ailo | http://alsa.opensrc.org/MultipleCards#Multiple_USB_Audio_Devices | 13:48 |
| ailo | No, sorry | 13:49 |
| ailo | This is irrelevant | 13:49 |
| zx81 | ok | 13:50 |
| zx81 | may be on day i find it | 13:51 |
| zx81 | good day to u | 13:52 |
| zx81 | ??? | 13:52 |
| zx81 | soon | 13:52 |
| zx81 | good MeTal stud | 13:52 |
| zx81 | hi !! (Oneiric Ocelot 11.10, cpu 2x 2.7Go, 2x1 Go Ram, amd64, ATI video card) problem freezing | 14:53 |
| zx81 | i cant find where its come ?, much of time its gone when i add more effect or after 10 min using, the sound crunch 1 min, and cut, and after all of windows GUI are break i'm obliged to reboot) | 14:56 |
| holstein | zx81: if you think its graphics related, try using the vesa driver | 15:03 |
| holstein | if not... just relax the JACK settings, and try again | 15:03 |
| zx81 | holstein, i have uninstall Flgx | 16:00 |
| zx81 | and its the same problem | 16:00 |
| zx81 | holstein, the sound become clipping | 16:01 |
| zx81 | and stop | 16:01 |
| ailo | zx81, Is it the same no matter what applications you use? | 16:02 |
| zx81 | i m obliged to reboot | 16:02 |
| zx81 | yes | 16:02 |
| ailo | Have you tried using a minimal amount of applications running? | 16:02 |
| zx81 | with skype same think, the sound became clipping and stop | 16:02 |
| ailo | You always have skype on? | 16:03 |
| zx81 | no | 16:03 |
| zx81 | yet i have try no start skype and test with jack | 16:03 |
| ailo | Does this happen when jack is not active? | 16:03 |
| zx81 | and its the same | 16:03 |
| zx81 | yes | 16:04 |
| ailo | It doesn't sound like it is a problem with the audio | 16:04 |
| zx81 | ??? manage memory ?? | 16:05 |
| zx81 | ??? manage USB | 16:05 |
| zx81 | its since oneiric install | 16:06 |
| ailo | Could be bad ram memory | 16:06 |
| zx81 | is there a file to fix memory /jack | 16:07 |
| ailo | You mean set maximum memory for jack? | 16:07 |
| ailo | You said you get the freeze even when jack is not on | 16:07 |
| zx81 | yes | 16:07 |
| ailo | So, it would not help | 16:08 |
| zx81 | ?? | 16:09 |
| zx81 | TY | 16:09 |
| zx81 | i come to install an old ubuntu studio stable to compare the kernel | 16:10 |
| ailo | zx81, Settings for jack memory is in /etc/security/limits.d/audio.conf | 16:10 |
| ailo | You can change the line: @audio - memlock unlimited | 16:10 |
| ailo | You could change it to: @audio - memlock 95 | 16:11 |
| ailo | Or less. Maybe 80 | 16:11 |
| ailo | NO, sorry | 16:11 |
| ailo | I forgot. It's in actual memory | 16:11 |
| ailo | Not percentage :P | 16:11 |
| zx81 | so ?? | 16:12 |
| ailo | You set it in MB | 16:14 |
| ailo | No, wait | 16:14 |
| ailo | kb | 16:14 |
| ailo | I have to double-check | 16:14 |
| zx81 | i must go | 16:16 |
| zx81 | ty | 16:16 |
| zx81 | ailo | 16:16 |
| ailo | Yeah, it's in kb | 16:16 |
| zx81 | ty | 16:16 |
