How to get my usb soundcard working on Debian 7.6

[ZabrielZacob]

Hello,

I am new in Debian as i am 4-5 year in ubuntu. I switched to Debian recently and it feels great. But i have a problem with sound configuration etc. How can i get my usb soundcard (Behringer UPhoria UM2) working and set it as default soundcard?

I am posting results of several commands

cat /proc/asound/cards :

Changing the index of snd-usb-audio to 1 does not work.

I am trying very hard last days to fix that problem with no success. Kernel i am running is 3.2.0-4-amd64. Last days i had compiled 3.14 but i dont know if i messed up the configuration for device drivers etc. I certainly want kernel 3.4-lowlatency configured but i dont know what device drivers should be included in menuconfig. Also i do not know for sure if it is a permission issue.

Thanks!

You may think about installing pulseaudio and pavucontrol, possibly the newer version in wheezy-backports, as it seems to just automagically get multiple sound cards working when they have your kind of problems--at least it's been solving those issues in Wheezy-based MX 14. I tested it with my problem audio, installing pulseaudio and removing my custom ~/.asoundrc that was necessary without it, rebooted, and all sound started working anyway.

So if i install pulseaudio everything will just work ? Will i have to reorder default soundcard or not? I think that if i will try using pulseaudio will lead to other problems. Is there a way of using pulseaudio without messing up alsa etc?

Finally fixed it! What i had to do was edit /etc/modprobe.d/alsa-base.conf adding these lines

Code: Select all

# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-hda-intel index=-2 model=auto vid=1002 pid=4383
options snd-hda-intel index=-2 model=auto vid=1002 pid=aa30

and editing the index of snd-usb-audio to 0 :

Code: Select all

# Usb Audio As First soundcard
options snd-usb-audio index=0

I hope this will help anyone with same problem!
