cfhowlett!sound15:10
ubottuIf you're having problems with sound, click the Volume applet, then Sound Preferences, and check your Volume, Hardware, Input, and Output settings.  If that fails, see https://help.ubuntu.com/community/Sound - https://help.ubuntu.com/community/SoundTroubleshooting - http://alsa.opensrc.org/DmixPlugin - For playing audio files,  see !players and !mp3.15:10
redlionI just installed fresh ubuntu studio 14.0415:10
redlioncfhowlett: my sound card is multi channel / usb15:11
cfhowlettredlion, I cant' diagnose - see the wiki link15:11
redlioncfhowlett: not sure it will help at this stage15:15
redlionI ll have a look though15:17
holsteinredlion: have you used JACK before?15:39
holsteini suggest *not* learning jack, and troubleshooting a random USB audio device that promises support for other operating systems than the one you are using15:40
holsteini would learn to use JACK with the internal audio device *then* move on configuring the USB device, which should be class compliant, and work "out of the box" (and likely does)15:40
redlionholstein15:43
redlionI already tried jack15:43
redlionI had an issue with gladish on my previous ubuntu classical environment15:43
redliontherefore I switched to ubuntu studio15:44
holsteinredlion: ubuntustudio *is* ubuntu15:44
redlionyep but fresh installed15:44
holsteincomparing, for example, ubuntustudio 14.04 and "classical" ubuntu 14.04, they are the same15:44
holsteinsame versions of all the software from the same repositories15:44
redlionholstein: gladish was not working with my ubuntu 14.04 install15:46
redlionI am not blaming ubuntu for this15:46
redlionI needed to start from a fresh conf therefore did I switch to ubuntustudio15:46
holsteinsure.. and im not addressing "blame" at all.. just that, ubuntustuduio 14.04's gladish will be the same as main ubuntu's gladish15:47
holsteinyou are welcome to fresh install as you please, im just saying, that wont get you a different, or "better" version of gladish, and using the usb audio device you have will be the same15:47
holsteinsame setup and config in jack15:47
redlionholstein I am aware of this15:48
holsteinwhat i usually do, and suggest is, simplify the config by using only one audio device15:48
holsteindisable or remove the internal audio device15:48
redlionthat is not the issue15:48
redlionI can see my card in pulseaudio15:48
holsteinsure.. pulse wont use the multi channels, though15:49
holsteinyou'll want jack to route like that15:49
redlionI am just not sure about the multichannels part15:49
holsteinredlion: sure.. jack, is the tool you want for that15:49
redlionok then let s say15:49
redlionactuallw my card is hw215:49
holsteinif you are not used to configuring jack, use the internal audio device with jack til you learn it15:49
holsteinredlion: those labels, "hw2" for example, can change between reboots15:50
redlionthen I need to set capture device on hw2,015:50
holsteinredlion: i do this, and suggest that you do this15:50
redlionyes ?15:50
holsteinredlion: remove the usb device, and reboot with *out* that device plugged in15:50
holsteinwith *only* the internal audio device15:50
redlionok15:50
holsteinsetup and configure JACK and test/use it, and learn to configure it15:50
redlionok15:51
holstein*after* you are comfortable with that, disable or remove the internal audio device (disable in the bios, for example) and configure the internal usb device in jack15:51
redlionI understand your logic15:51
holsteinthis is *not* a fix, or the only way  to do it. you can ask in #opensourcemusicians about labeling those devices in alsa more permanently if you prefer15:51
holstein!proaudio15:52
ubottuFor information on professional audio tools in Ubuntu, see https://help.ubuntu.com/community/UbuntuStudio/ProAudioIntro15:52
holstein^ the configuration of jack still looks like that15:52
redlionk holstein I will try play a bit more with qjackctl15:56
