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