rock_star14Hey there im new here, I am curious if studio hardware such as digidesign 002 & 003 and focusrite octopre ADAT racks are compatible with this OS and DAWS that are available on this OS cheers07:28
rock_star14like has anyone tried hardware such as these on ubuntu studio?07:28
IotaSpencerhow do I stop the buzzing after pulseaudio and jack start fighting each other14:43
IotaSpencerhello?14:47
IotaSpenceralright, what happens is, I install ubuntu studio, i install the updates from apt-get upgrade for the first time, then after that restart, I get buzzing when system sounds come on, including skype, and any sound that comes through is garbled15:16
IotaSpencerwithout the updates its fine, once I get the updates it shits the bed15:17
holstein!language | IotaSpencer15:25
ubottuIotaSpencer: The main Ubuntu channels require that you speak in calm, polite English. For other languages, please visit https://wiki.ubuntu.com/IRC/ChannelList15:25
holsteinIotaSpencer: will you try using the older kernel? and test?15:25
holsteinIotaSpencer: if you are not using jack, then its *not* jack and pulse audio "Fighting each other"15:26
IotaSpencerwell, I have jack and pulse audio installed15:27
IotaSpencerand it only happened after pulse was installed15:27
IotaSpencerand how do you try an older kernel ._.15:27
IotaSpencerI've always updated kernels, not downgraded15:27
holsteinIotaSpencer: pulse was installed by default15:28
holsteinIotaSpencer: so, pulse installation did *not* trigger this15:28
IotaSpencerThen what did15:29
holsteinIotaSpencer: you stated you updated.. so, im suggesting test with the older kernel first, and see if its the kernel update15:29
IotaSpenceralright, then how do I choose an older kernel15:30
holsteinIotaSpencer: at boot, from grub15:31
holsteinIotaSpencer: if grub is hidden, you can use shift at boot.. you'll see your currect kernel and previous kernels.. go into the previous menu, and see if there are any older kernels15:32
holsteinIotaSpencer: please dont spend much time looking for them, or waste more than about 8 minutes trying to do this15:32
holsteinIotaSpencer: this is *not* a fix, but a troubleshooting step..15:32
IotaSpencerwell, rebooting now15:33
holsteinIotaSpencer: i do not konw if you have older kernels, nor if this is the issue. its just something that can cause the issue you state, if, indeed,  everything was OK prior to updating15:33
IotaSpencerkernels aren't the issue15:42
holsteinIotaSpencer: if i may, please tell me how you determined that..15:42
IotaSpencertried both that I had and neither fixed the problem15:42
holsteinIotaSpencer: sure. what exactly is the problem?15:42
IotaSpencer>_<15:43
holsteinIotaSpencer: please tell me exactly the issue15:43
holsteinIotaSpencer: do you even start JACK? no? correct?15:43
IotaSpencerthat systems sounds buzz + skype sounds are garbled15:43
holsteinIotaSpencer:  you just boot the system, and hear buzz?15:43
holsteinIotaSpencer: sure.. but, you are not using JACK, correct?15:43
IotaSpencerthe bloop on skype turns into a buzz15:43
holsteinyou never start jack? and you never added any PPA's?15:43
IotaSpenceronly ppa i have is weechat15:44
holsteinIotaSpencer: and, you never start jack, correct?15:44
IotaSpenceri thought it started itself15:44
holsteinIotaSpencer: no15:44
holsteinIotaSpencer: jack is not something that when installed, is running15:44
holsteinIotaSpencer: so, you are not using jack, correct?15:45
IotaSpenceralright then how do i start it to see if it helps it15:45
IotaSpencerjack is installed15:45
holsteinIotaSpencer: no.. jack wont "help" this15:45
IotaSpencer>_<15:45
holsteinIotaSpencer: jack is not for casual audio like that15:45
holsteinIotaSpencer: its a professional audio sound server.. meant to do advanced routing, and provide lower latency15:45
holsteinIotaSpencer: please do *not* throw a new issue into the mix at this point. i am only collecting facts and details15:46
IotaSpenceralright then what other facts do you need15:46
holsteinIotaSpencer: please confirm you are not using JACK by running "ps aux | grep jack" in a terminal.. you can use a pastebin15:46
IotaSpencerthe grep is all that shows up15:47
holsteinwhile in the terminal run "aplay -l" and "arecord -l" and share those via pastebin15:47
holsteinIotaSpencer: so, jack is not running.. and is not able to be causing the issue here15:47
holsteinIotaSpencer: there is no fight between pulse and jack going on.. jack is out of the equation.. for future reference15:48

IotaSpencer@ holstein15:56
* IotaSpencer waits16:04
holsteinIotaSpencer: ok.. if it were me, i would pull up the live CD again, and test that no issues have occured that have caused my hardware to break16:04
IotaSpencero16:04
holsteinIotaSpencer: then, i would look into (while the live CD is up) what version of alsa is there,.. and step my installed version back down to that version if its not the same16:04
holsteini would then run pavucontrol and alsamixer and tweak *everything* not trusting the lables16:05
holsteinlabels*16:05
Iota[web]ok and how do I check which version of alsa each uses?16:15
holsteinIota[web]: i use a package manger.. i like synaptic as a GUI16:16
Iota[web]hmm16:23
Iota[web]Alright the one installed to the live usb is the same as the one in the repo16:24
holsteinIota[web]: ok.. so, its not alsa, nor the kernel, it seems16:30
holsteinIota[web]: what else is there? your user config? you can try the guest account and test audio16:30
holsteintest known-good simple audio files.. not 3rd party applications like skype16:31
Iota[web]so like any of my music you mean?16:31
holsteinIota[web]: no.. i mean specifically what i said.. a known-good simple audio file.. a well supported oog file that you know plays16:32
Iota[web]well I don't16:32
Iota[web]lol16:32
holsteinnot sykpe, or a downloaded mp3 that requires a codec16:32
Iota[web]I don't have any oogs16:32
holsteinsomething you *know* plays, and is supported, and doesnt require anything outside the repos16:32
Iota[web]I don't know what is supported and whats not16:33
holsteinIota[web]: there should be many sounds included in the system, but, again, dont overthink this.. its a troubleshooting step, not a fix16:33
holsteinIota[web]: ogg is open and supported by default, which is why i use, and suggest it for testing purposes16:33
Iota[web]alright, and where would I find the sounds, because I've never actually looked for sounds other than the mp3's I listen to16:34
holsteinIota[web]: i would use one that i konw works.. use what works on the live CD without issue16:34
holsteinIota[web]: anything you have that you know works well, in the default player16:34
Iota[web]=_=16:34
holsteinIota[web]: i dont understand what that is16:35
Iota[web]I don't have anything readily accessible except for mp3s16:35
holsteinIota[web]: then, use them, friend.. just keep in mind, you are assuming mp3 support is not the issue16:35
holsteinIota[web]: so, if you like, somewhere down the line, remove mp3 support from this test equation16:35
holsteinIota[web]: test audio as the guest user.. is it broken as the guest user as well?16:36
Iota[web]i'm on the live usb user16:36
Iota[web]'Live session user'16:37
holsteinIota[web]: ok16:37
Iota[web]everything works16:37
Iota[web]no ifs ans or butts16:37
holsteinIota[web]: then, test an audio file, keep that audio file in mind. and reboot your "broken" system, and test the *exact* *same* *file* the *exact* *same* way* in the guest user account16:37
Iota[web]alright the music file works, now to switch to the computer part and try16:40
Iota[web]ok, mp3 plays fine both places16:46
holsteinIota[web]: as guest user?16:46
Iota[web]yep16:46
Iota[web]'Guest' is my user16:46
holsteinIota[web]: ok.. so try again as your normal user, the *same* file the same way16:47
Iota[web]ok16:47
IotaSpencerfile could not be opened wut16:48
holsteinIotaSpencer: im not following..16:49
IotaSpenceroh, it was still connected as guest, had to remount it as mine16:49
IotaSpencerand the file still work16:50
IotaSpencers16:50
holsteinIotaSpencer: ok, so your system wide audio is *not* broken.. what is not working?16:50
IotaSpencerskype calls are garbled, and skype sounds make the sound buzz till I close skype16:50
IotaSpenceror until I restart pulseaudio16:51
holsteinsure, but that is an issue with skype not your system sound, as you previously stated16:51
holsteinthere is no system wide audio issue16:51
holsteinjust skype, correct?16:51
holsteinIotaSpencer: where did you get skype? the resos?16:52
IotaSpencerright, but it only happens after the first apt-get update + upgrade after the install16:52
holsteinrepos*16:52
holsteinIotaSpencer: no.. it just happened now, friend16:52
holsteinIotaSpencer: its happening from skype.. now16:52
holsteinIotaSpencer: regardless.. where did you get skype?16:52
IotaSpenceryes, after the apt-get update + upgrade till I uninstall everything16:52
IotaSpencerskype.com16:52
IotaSpencerwhereelse16:53
holsteinIotaSpencer: the partner repo16:53
IotaSpencer??16:53
holsteinIotaSpencer: please try removing that skype, and installing the partner repo version16:53
IotaSpencerwhats the partner repo ppa or whatever16:53
holsteinIotaSpencer: the partner repo *is* the repo16:54
holsteinIotaSpencer: please relax.. i am finding resources for you16:54
holsteinIotaSpencer: this looks OK.. http://www.noobslab.com/2014/01/skype-released-new-version-install-in.html though, i would consider not installing skype-wrapper16:56
holsteinregardless, now you know where the issue is.. and its not with the system, or any ubuntu or linux packages16:56
holsteinIotaSpencer: remove the version you have installed first16:56
IotaSpencero_O17:03
IotaSpencerthat fixed it17:03
* IotaSpencer is confoozed17:03
IotaSpencerI'm guessing I should just accept it and get on with my life17:06
holsteinIotaSpencer: let skype know you had an issue with their product17:10
holsteinIotaSpencer: the biggest issue with this is tracking it down, and not assuming anything17:11
holsteinIotaSpencer: we are not allowed to know what skype is doing, so, we cant support it, but they are always welcome to.. they = skype maintainers17:11
IotaSpencerand its back, I restarted and the buzzing is back17:14
holsteinIotaSpencer: the buzzing in skype?17:14
IotaSpenceryep17:14
holsteinIotaSpencer: make certain skype is causing the issue, and let them know17:14
holsteinyou can file bugs against it..17:14
holstein!bug17:15
ubottuIf you find a bug in Ubuntu or any of its derivatives, please file a bug using the command « ubuntu-bug <package> » - See https://help.ubuntu.com/community/ReportingBugs for other ways to report bugs.17:15
holsteinbut, upstream would really be the "best" way to deal with it17:15
IotaSpencerit worked for a bit when I installed it like you said, but once I restarted it started buzzing17:15
holsteinIotaSpencer: restarted what?17:15
IotaSpencermy computer17:15
holsteinIotaSpencer: ok.. let the skype maintainers know you have an issue with their product17:16
IotaSpencero,o17:25
IotaSpencerIf I reinstall it works again17:25
holsteinIotaSpencer: sure.. let them know17:26
OvenWerk1I found when I first started skype that my speaker volume was too high and I had noise. Once I lowered it a funny thing happend and skype took over controling the level.17:35
holsteinIotaSpencer: yeah, that is true ^17:38
holsteintry setting control for skype to manual17:38
holsteincould be just overblowing the settings17:38
IotaSpencerI never set skype to manage my sound though lol17:39
holsteinIotaSpencer: you dont have to17:39
OvenWerk1I didn't either it just did17:39
IotaSpencerunticked it17:39
holsteinIotaSpencer: you can confirm those settings to be sure. because that is the default setup17:39
wickedheadacheso i should stop updateing the general kernal and start the rt update at 13.10?20:05
holsteinwickedheadache: 13.10 is nearly EOL20:06
holsteinthere is no rt kernel. just the lowlatency one.. if thats what you are referencing20:06
wickedheadachenope referenceing the realtime kernal20:11
wickedheadachei know it's ot supported20:11
holsteinwickedheadache: there is no RT kernel, so you are probably using it from a PPA?20:11
wickedheadachebut its what i need20:11
wickedheadachenot sing it yet20:12
wickedheadacheafaik 12.04 was last rt kernal20:12
holsteinwickedheadache: you can always make whatever kernel you like20:13
holsteinyou should try the lowlatency kernel, and the generic ones20:13
wickedheadachecorrect20:13
holsteini have hardware that actually gets lower latency do to better hardware support in the generic kernels of late20:13
wickedheadachebut i don't want to g past a version where work had ended on rt20:14
holsteinwickedheadache: they are labeled20:14
holsteinwickedheadache: you should try the lowlatency ones20:14
wickedheadachenot from where i've been looking20:14
holsteinwickedheadache: there is really no need anymore for hard coded rt kernels like that20:14
holsteinwickedheadache: look in your actual system and setup with the actual kernel running20:14
holsteinwickedheadache: test first hand20:14
wickedheadachethat what they said about 64.bit systems20:15
holsteinwickedheadache: they?20:15
holsteinwickedheadache: *you* try it, friend.. you can try it with the live CD20:15
wickedheadacheyes they the speculators20:15
wickedheadachei have tried it20:15
holsteinotherwise, there are many PPA's with rt kernels.. and other ways to run whatever kernel you like20:15
wickedheadacheand i will again20:15
wickedheadachexD20:15
holstein14.04 and 12.04 are soon to be the only  supported versions20:16
holsteinneither have rt kernels20:16
wickedheadacheit is likely i'll have both an rt and general "low latency" just for hw support and fixes etc20:16
holsteinhave what you like..20:16
holsteinif your question is, should i stop upating the rt kernel, my answer is, use a supported kernel20:17
holsteinkxstudio ppa's are well trusted and supported..20:17
wickedheadacheso stop at 12.04 and update from there, maintain that rt kernal...and use a supported kernal for general use ty20:18
wickedheadachehmm20:18
holsteinwickedheadache: 12.04 has no rt kernel20:19
holsteinwickedheadache: run 14.04 with whatever kernel you like, if you are comfortable supporting them on your own20:19
holsteinwickedheadache: 14.04 is what is suggested to be using20:19
holsteinwickedheadache: you likely dont need an RT kernel anymore.. i find, first hand, on *all* my gear, i dont need it anymore20:19
holsteinif you find you want, or need RT kernel, use one.. there are ppa's20:20
holsteinyou should be using 14.04.. but, 12.04 is still supported if you prefer20:20
holsteinneither provide out of the box rt kernels20:20
wickedheadachenor does kxstudio?20:20
holsteinwickedheadache: kxstudio provides a PPA that many use in ubuntustuduio20:21
holsteinwickedheadache: you can ask kxstudio if they have an rt kernel20:21
wickedheadacheit really never was supported20:21
holsteinwickedheadache: what really never was?20:21
holsteinwickedheadache: there was an officially supported rt kernel in 9.10.. that kernel was pulled forward to 10.0420:21
wickedheadachert kernals...well les then others20:21
holsteinwickedheadache: then, we added the officially supported lowlatency kernel20:21
wickedheadachei'm glad it hung on for so long20:21
holsteinwickedheadache: there is no need for RT kernels. you should test first hand and see for yourself20:22
wickedheadachei wonder why you say tere is o need?20:22
wickedheadachewhat do you do with your pc?20:22
holsteinwickedheadache: our upstream https://wiki.debian.org/DebianMultimedia#Realtime_kernel20:22
holstein"The Debian Multimedia team is not working on including a kernel image with the realtime-patches applied in Debian. Much of the realtime-patches have been accepted in the mainline kernel, to the point that for most purposes the stock Debian kernel is suitable even for realtime-like work."20:22
holsteinwickedheadache: i work on what i need to work on20:23
holsteinwickedheadache: i can facilitate realtime effects processing, and software synths live in realtime with the lowlatency kerne20:23
holsteinkernel*20:23
holsteinthat is all RT is needed for20:23
wickedheadachenice link xD20:23
wickedheadachei think it gets confusing what happens between low lateny and real time...quick doesn't mean everything asap20:24
holsteinwickedheadache: ubuntu is not working on one either.. but, we provide a lowlatency one that is an nice "balance" as more and more of the generic kernel becomes appropriate20:24
holsteinwickedheadache: do you do realtime effects processing?20:25
wickedheadacheuh yea you could say that20:25
holsteinwickedheadache: ?20:25
holsteinwickedheadache: do you?20:25
holsteinwickedheadache: do you use the machine to provide effects such as distortion for a guitar in realtime?20:26
wickedheadacheif softwae needs it then yes20:26
holsteinwickedheadache: software doenst20:26
holsteinwickedheadache: do you?20:26
wickedheadacheuh ok20:26
holsteinwickedheadache: do you use the computer for realtime effects processing?20:26
holsteinwickedheadache: like a stompbox emulator for a real time performance on the guitar?20:26
wickedheadachesee this is what people don't seem to understand20:27
holsteinwickedheadache: correct, thats why im asking..20:27
holsteinwickedheadache: if you dont do it live, you dont need lower latency settings20:27
holsteinwickedheadache: do you do software synths live, as an instrument?20:27
wickedheadachereal time applies to many things20:27
holsteinwickedheadache: not really20:27
holsteinwickedheadache: it applies specifically to needing sound to happen in "realtime"20:27
wickedheadacheits not simply, will someone use thi or that20:28
wickedheadacheand not for just audio20:28
holsteinwickedheadache: you play the guitar, and the affected sound happens in relative realtime, so you can use it, like a stompbox20:28
wickedheadachei get that20:28
holsteinwickedheadache: or, when you play a MIDI keyboard, you want the synth sound to occur relatively in sync with pushing the keys20:28
holsteinnot 30 miliseconds later20:29
wickedheadachelow latency may stil not be able to multi task in real time?20:29
holsteinif not doing those 2 things, then, 30 miliseconds doesnt matter20:29
wickedheadachehehe20:29
holsteinwickedheadache: correct, RT is *not* relating to multitasking, or a "better" system. or "more performance"20:29
holsteinwickedheadache: its specificialy only for that.. lower latency20:29
wickedheadachetiming is everything in music particulrly live20:29
wickedheadachewow20:30
holsteinwickedheadache: sure.. and im specificallly referencing live as the use case20:30
holsteinwickedheadache: *only* live20:30
holsteinwickedheadache: otherwise, it dosnt matter if, for example, you have a session loading in ardour, and you press play, and 40 miliseconds later is plays back20:30
wickedheadacheso this is what happened to the rt kernal? it was taken over by pro audio?20:30
holsteinthe time there is irrelevant, and doesnt effect the quality of the work20:30
holsteinwickedheadache: the RT kernel is gone, friend20:30
holsteinwickedheadache: the patches were mostly integrated, as the link states, into the generic kernels20:31
wickedheadacheit will be back i get the feeling low lat will not suit my needs20:31
wickedheadachebut i will ty it20:31
holsteinwickedheadache: if you need lower latency, you may20:31
holsteinbut the kernel is only one part of it20:31
holsteinthe driver support is more important to facilitating lower latency20:32
wickedheadachelatency is not my only concern20:32
holsteinas i stated above, i can get lower latency with a generic kernel with a particular USB device20:32
wickedheadachethat it is driver and hw support is vital20:32
holsteinthat is not related to the RT patch, but the driver support20:32
holsteinso, if you want lower latency, or need it, which im still not sure you do.. the kernel patch is only one part of it20:32
wickedheadacheso how woul an ha enviroment play into Low lat systems?20:33
holsteinwickedheadache: a "ha environment" ?20:33
wickedheadachedo i get similar things going down the ha path?20:33
holsteinwickedheadache: either you need higher priority or not20:34
holsteinwickedheadache: you determine if you do, then do what needs to be done20:34
wickedheadacheor both20:34
holsteinwickedheadache: not following20:34
holsteinwickedheadache: as i said, these patched kernels are just part of the equation20:34
holsteinwickedheadache: driver suppport is much more crucial. and a patched kernel will likely not "Fix" that in any way20:35
wickedheadachein an ha / cloud enviromeny many cpus hd's etc will be used at once20:35
holsteinwickedheadache: for proaudio, you would want to track to a different drive than the OS is on, ideally20:35
wickedheadachethe general 14 version supports much of the ground work for a cloud or share resouces20:36
holsteinwickedheadache: otherwise, no such ha patches will really do much to facilitate an audio production enviroment20:36
holsteinwickedheadache: sure.. and thats nothing to do with audio20:36
wickedheadachecorrect20:36
holsteinwickedheadache: or video20:36
holsteinwickedheadache: if you want or need waht it provides, use it20:36
holsteinwickedheadache: if the question is, will ha help me in audio.. i dont see anything that suggests that20:36
wickedheadachemuch of the performane increase woon't be noticable if the pc is not setup correctly anyway20:37
holsteinhard drive access will not facilitate or improve driver support20:37
holsteinwickedheadache: is your hard drive the bottleneck for your audio production? for me, its not20:37
wickedheadacheit always is xD20:37
holsteinso, im not looking for kernel patches to address an issue i dont have20:37
holsteinwickedheadache: i doubt that it is20:37
wickedheadachebut i guess i won't know how well low lat supports clouds until its tried20:38
holsteinbut again, if you want/need it, make it happen20:38
holsteinwickedheadache: clouds?20:38
holsteinwickedheadache: servers?20:38
holsteinwickedheadache: you should use the generic on a server.. its what the server OS ships with20:38
wickedheadacheright i will i just want some idea of future conflicts and bugs i guess20:38
holsteinwickedheadache: you dont want an audio specific rt or lowlatency for a server machine20:38
holsteinwickedheadache: if you are not doing audio production, you are not in the correct zone20:39
wickedheadacheaudio is part of it20:39
holsteinwickedheadache: sure.. and its not going to help you on a server like that20:40
wickedheadacheit sure would20:40
holsteinwickedheadache: you are in the wrong place.. and neither an rt or lowlatency kernel is correct for a server20:40
holsteinwickedheadache: if you think it would, feel free to try it20:40
holsteinwickedheadache: its not intended for what you are talking about20:40
wickedheadachethere is no right place for this stuff xD20:40
holsteinwickedheadache: yes.. a server channel20:40
wickedheadacheintentions are relevent20:40
holsteinwickedheadache: the kernel the server version ships with will be appropriate20:40
wickedheadacheright unless you built the server20:41
holsteinwickedheadache: use what you like, friend. the lowlatency and rt kernels are not for yout task20:41
wickedheadacheit seems they are by our discussion so far20:41
holsteinwickedheadache: ?20:41
wickedheadachei'm glad your around to chat about stuff20:42
holsteinanyways.. good luck and try a server community. cheers@20:42
