| coelebs | hello | 09:38 |
|---|---|---|
| coelebs | can't get usb audio interface working with jack | 09:38 |
| coelebs | and what was the other channel, #opensourcemusician or something? | 09:47 |
| SirRiffsAlot | Hey people! I've put E17 as the desktop environment on 14.04, but the Sound and Video-menu sometimes comes up empty (where ardour and all that should appear), and sometimes it works normally. Could this have to do with UbuntuStudio or the desktop environment? ... or both? | 12:36 |
| coelebs | best way to reset pulseaudio and jack to factory default? | 12:41 |
| zequence | coelebs: It's mainly about settings. Pulseaudio may have both user settings and system-wide settings | 14:39 |
| zequence | ..while jack only has user settings | 14:40 |
| zequence | delete ~/.jackdrc and ~/.config/jack to loose both jack1 and jack2 settings | 14:41 |
| zequence | (the second is a folder) | 14:41 |
| zequence | qjackctl settings are at ~/.config/rncbc.org/QjackCtl.conf | 14:42 |
| zequence | You will only have ~/.pulse, or something like that, if you created it yourself | 14:43 |
| zequence | for systemwide pulse settings, backup the folder /etc/pulse, remove the original, then reinstall pulseaudio | 14:43 |
| zequence | To reinstall a package, do: sudo apt-get install --reinstall <packagename> | 15:04 |
| coelebs | thx zequence i'm trying that now | 15:19 |
| coelebs | hmm pulse is not working | 15:35 |
| coelebs | if i start jack with "/usr/bin/jackd -P80 -p2048 -t2000 -dalsa -dhw:CODEC -r48000 -p256 -n3 -s" i get the settings i want for jack | 15:36 |
| coelebs | how would i make jack start like that every time? | 15:37 |
| coelebs | this pulseaudio issue is really annoying since i only need it for chrome... but i need it real bad :D | 15:40 |
| holstein | i would just stop jack, and use pulse | 15:54 |
| holstein | you should be able to just start jack, and route pulse sources.. | 15:54 |
| coelebs | yeah i was | 15:55 |
| coelebs | then i booted :/ | 15:55 |
| coelebs | also pulse doesn't care if jack is running or not | 15:56 |
| holstein | coelebs: it actually does.. thats likely the issue you are having.. is it not? | 16:00 |
| holstein | i would test pulse without jack running, or having been running.. | 16:01 |
| coelebs | i mean i stopped jack and tried to run pulse | 16:02 |
| coelebs | jack is not running at the moment and pulse wont start | 16:02 |
| holstein | coelebs: try it with having *never* used jack | 16:02 |
| coelebs | just booted a minute ago | 16:03 |
| holstein | you dont need to "start" pulse.. it'll just run, and be running, and restart automatically.. if not, how are you trying to start it? and what are the errors? | 16:03 |
| coelebs | well cannot open mixer | 16:03 |
| holstein | coelebs: pavucontrol? what erros? what about alsamixer? | 16:03 |
| holstein | errors* | 16:04 |
| coelebs | connection to pulseaudio failed. automatic retry in 5s | 16:04 |
| holstein | coelebs: sure.. but that could be due to a jack start up that you tried.. are you autostarting jack? | 16:04 |
| coelebs | hmm alsa/pulse plays now trough pc speaker | 16:05 |
| holstein | sure,a nd thats how its meant to be.. by default, at startup | 16:05 |
| coelebs | no autostart | 16:06 |
| coelebs | well used to had but removed it | 16:06 |
| holstein | coelebs: used to have autostarting jack? | 16:06 |
| coelebs | i used to route pulseaudio sink to jack all the time | 16:06 |
| holstein | which is fine.. but, that can be causing issues with jack | 16:07 |
| coelebs | now i want this with usb audio card too | 16:07 |
| coelebs | never had issues with jack before this new audio interface | 16:07 |
| holstein | coelebs: i would route the pulse source in qjackctl to the usb device im running jack on | 16:07 |
| holstein | coelebs: it doesnt appear you are having issues with jack now on that interface.. | 16:08 |
| coelebs | well whadda you say | 16:08 |
| coelebs | now jack aint working anymore | 16:08 |
| coelebs | sorry jack just needed to be started | 16:09 |
| coelebs | so jack is working on usb interface, pulseaudio is working on internal sound card, pulseaudio sink is not working and pulseaudio mixer is not opening | 16:10 |
| coelebs | i had them all working until reboot | 16:10 |
| coelebs | so maybe the mixer is the only real issue | 16:13 |
| coelebs | i'm lacking all pulse config files too | 16:14 |
| holstein | coelebs: i would just relax about it | 16:17 |
| holstein | coelebs: if i can, i'll just disable the insternal audio when i want USB interface only | 16:17 |
| holstein | those alsa labels can change between boots | 16:17 |
| holstein | coelebs: when you say "pulse audio mixer", you mean, pavucontrol ? what do you mean it "isnt opening"? its not starting? or reaching a device? | 16:18 |
| coelebs | lemme take a screenshot | 16:18 |
| holstein | i would try and remove variables and test | 16:19 |
| coelebs | but i'd need the sink... to listen music from youtube and play my guitar trough guitarix on it | 16:19 |
| holstein | wow | 16:19 |
| holstein | coelebs: i dont think you'll get an acceptable latency with either of those devices | 16:19 |
| coelebs | guitarix is acceptable already | 16:20 |
| coelebs | and pulseaudio latency doesn't matter | 16:20 |
| holstein | coelebs: not with pulse routing trouhg it | 16:20 |
| holstein | coelebs: pulse is going to route through jack.. so, the latency im talking about is the jack setup latency | 16:20 |
| holstein | coelebs: but, the playback of the youtube vids are not the issue | 16:21 |
| coelebs | http://imgur.com/Zkqc3E8 | 16:22 |
| holstein | coelebs: sure.. and you shouldnt assume thats a problem with pulse | 16:22 |
| holstein | coelebs: what would i do? what i sugested above was disable the internal audio device and try.. | 16:22 |
| coelebs | hmm i don't get it | 16:22 |
| holstein | coelebs: i would *not* start jack, and try and get pulse running on the USB device | 16:23 |
| holstein | coelebs: take the problem in parts.. not all at once | 16:23 |
| holstein | i like using "aplay -l" and "arecord -l" to see what alsa is using | 16:24 |
| coelebs | well what do i need to do to get pavumixer working? | 16:24 |
| holstein | coelebs: its not that its not working, friend | 16:25 |
| holstein | coelebs: its that something is not configured properly to do what you are trying to do.. | 16:25 |
| holstein | pavucontrol* | 16:25 |
| holstein | !info pavucontrol | 16:25 |
| ubottu | pavucontrol (source: pavucontrol): PulseAudio Volume Control. In component universe, is optional. Version 2.0-2 (trusty), package size 111 kB, installed size 962 kB | 16:25 |
| holstein | is that what you are talking about? | 16:25 |
| coelebs | yes | 16:25 |
| holstein | coelebs: have you tried disabling the internal audio device in the bios? have you tried using pulse with the USB deivce *without* starting jack? have you tried using jack on the USB device with the pulse dbus and routing the pulse sources to the USB device in qjackctl? | 16:26 |
| coelebs | i'll try disabling the internal audio | 16:27 |
| coelebs | let's see where we get | 16:27 |
| holstein | when you do, pulse will only see the one usb device. when you reboot the machine, *dont* start jack.. just test pulse on the USB device.. | 16:28 |
| holstein | if you cant disable the device in the bios, dont waste time on this.. its not a "Fix" for you.. its just a step for you to learn how to configure the devices | 16:28 |
| coelebs | disabled internal but pulse is not co-operating | 16:35 |
| holstein | coelebs: cool.. just ask a question if you have one | 16:35 |
| coelebs | at first it did | 16:35 |
| holstein | coelebs: "pulse is not cooperating" is a statement | 16:36 |
| holstein | if you had pulse working on the USB device, then, tried to start jack, then thats waht i would expect | 16:36 |
| coelebs | no audio and no pavucontrol | 16:36 |
| coelebs | jack is not running | 16:36 |
| holstein | coelebs: "at first it did" implies to me that the audio *did* work? | 16:36 |
| coelebs | yes out of the box | 16:37 |
| holstein | coelebs: what do you mean "no pavucontrol"? | 16:37 |
| holstein | the application wont start? | 16:37 |
| coelebs | yeah it can't connect to pulseaudio server | 16:37 |
| holstein | its just a mixer.. if you say "no pavucontrol", to me, that implies it doesnt start.. is that the case? | 16:37 |
| holstein | coelebs: ok.. then, *stop* using pavucontrol for now | 16:37 |
| coelebs | ok | 16:38 |
| holstein | coelebs: the creators of that USB device dont promise you to be able to use it with pulse, alsa, or control it with pavucontrol | 16:38 |
| holstein | coelebs: pulse, alsa, pavucontrol, linux, ubuntu, and ubuntustudio are not doing anything to prevent it from working | 16:38 |
| holstein | coelebs: so, to clarify, you reboot, with *only* the usb audio device, and things work fine? | 16:39 |
| holstein | audio and youtube and whatever else? | 16:39 |
| holstein | coelebs: if so, please now try starting JACK with the usb audio device. *dont* test pulse sources, or youtube first.. please test something that uses jack like the guitarix setup.. and see that its working as expected | 16:40 |
| coelebs | i just rebooted, disabled internal audio and no sound on youtube | 16:40 |
| holstein | coelebs: the "no sound on youtube" issue has more variables.. flash for example | 16:41 |
| holstein | *please* dont test youtube now.. just do pulse and jack.. with known good simple sources | 16:41 |
| holstein | are you able to use the USB device with guitarix? | 16:41 |
| coelebs | o | 16:42 |
| coelebs | no | 16:42 |
| coelebs | only if i run "/usr/bin/jackd -P80 -p2048 -t2000 -dalsa -dhw:CODEC -r48000 -p256 -n3 -s" | 16:42 |
| holstein | coelebs: you should be able to use qjackctl for that | 16:46 |
| holstein | otherwise, you may not be able to route pulse through jack using that custom startup | 16:46 |
| holstein | coelebs: as i see it, thats the issue. you are starting jack manually.. and the pulse dbus is not running from that script | 16:47 |
| coelebs | aight | 16:47 |
| holstein | those settings are not going to be acceptable for guitarix, anyways | 16:47 |
| holstein | thats going to be like 40+ms | 16:47 |
| holstein | which is what i would expect | 16:47 |
| holstein | i must go.. you can try #opensourcemusicians | 16:48 |
| coelebs | thanks for help | 16:48 |
| zequence | coelebs: If you want pulseaudio to work while running jack you have two choices. 1, use jackd2 with pulseaudio-module-jack | 18:01 |
| zequence | 2, use jack on one audio device, and pulse on another | 18:02 |
| coelebs | it's magically working now even after boot | 18:02 |
| zequence | As for option one, you still need to select jack as the output source for pulseaudio, after starting jack | 18:02 |
| coelebs | i bruteforced myself right settings | 18:02 |
| zequence | Well, I'm happy it's working then | 18:02 |
| coelebs | it says 16ms latency but my interface seems to have hot wired playtrough on mic | 18:03 |
| coelebs | thank you all who helped | 18:06 |
| Jesse__ | Hello | 18:48 |
| holstein | o/ | 18:48 |
| Jesse__ | is it advisable to add in the KX Studio repos | 18:49 |
| holstein | if you want them, go for it | 18:49 |
| holstein | its not ubuntustuduio anymore, so you get support from falk at kx | 18:50 |
| holstein | !ppa | 18:50 |
| ubottu | A Personal Package Archive (PPA) can provide alternate software not normally available in the offical Ubuntu repositories - Looking for a PPA? See https://launchpad.net/ubuntu/+ppas - WARNING: PPAs are unsupported third-party packages, and you use them at your own risk. See also !addppa and !ppa-purge | 18:50 |
| holstein | not that there is anything wrong with kx.. its just not ubuntustudio anymore.. thats al | 18:50 |
| holstein | all* | 18:50 |
| Jesse__ | Well I meant I am Installing Ubuntu Studio then adding the repos to perhaps add some of their apps not found in Ubuntustudio | 18:51 |
| holstein | Jesse__: correct | 18:51 |
| holstein | Jesse__: you will have ubuntustudio, then, add the repos that are not supported by US | 18:51 |
| holstein | Jesse__: if you want/need them, add them. but, you dont get ubuntustudio or ubuntu support.. you get support from kxstudio at that point | 18:51 |
| holstein | as i said, nothing wrong with kxstudio.. its just not our product, and we dont/cant maintain it | 18:52 |
| Jesse__ | By adding a single kx studio app you get no support or do you mean by adding the repos the system will change into kx studio during updates | 18:52 |
| holstein | Jesse__: what i mean is specifically what is stated.. | 18:53 |
| holstein | ppa's are not supported.. officiall | 18:53 |
| holstein | we dont make the software in them, and cant support or guarantee them | 18:53 |
| Jesse__ | Right but you will still support the rest of the system | 18:54 |
| holstein | if you add the sources, you are running kxstudio.. which means that you get support from falk | 18:54 |
| holstein | Jesse__: its not ubuntustudio anymore | 18:54 |
| holstein | Jesse__: there are quite a few differences... and you would get support for kxstudio from kxstudio | 18:54 |
| Jesse__ | Usually when someone adds a ppa which is commonly done they still get support from the base system | 18:55 |
| holstein | Jesse__: ppa's are not supported | 18:56 |
| Jesse__ | not for the ppa itself but for everything else | 18:56 |
| holstein | Jesse__: thats why i say, you may have issue adding the unsupported sources.. if you are OK with that risk, as the ppas themselves will outline when you insatll them, go for it | 18:56 |
| holstein | Jesse__: the kxstudio ppas are responsible for *most* of the pacakges in your system at that point | 18:57 |
| Jesse__ | ok thanks appreciate your help | 18:57 |
| holstein | Jesse__: i happen to work with kxstudio as well, and im familiar with the process | 18:57 |
| Jesse__ | ok so by adding their repo/ppa it supplants the US packages | 18:57 |
| holstein | Jesse__: if you add the kstudio ppa's, you will have *mostly* kxstudio pacakges, and be running kxstudio.. not ubuntustudio | 18:57 |
| Jesse__ | I see | 18:58 |
| holstein | if you want them, go for it | 18:58 |
| Jesse__ | Ok rebooting, installation of US is complete take care :) | 18:58 |
| holstein | o/.. | 18:58 |
| SirRiffsAlot | Does anyone know which of the latency-kernels work best for a Komplete Audio 6 (USB-driven sound card)? In terms of xruns et cetera | 22:29 |
