alsamixer and default soundcard

English Hardware
#1

Hi all!

I have behringer UCA202 usb card, after plug to usb, it just works :), I have only small problem with alsamixer, which still shows by default my integrated HDA Intel, I could switch it by F6 or by alsamixer -c 1 … no problem, but I expect that default card is now plugged “USB audio”, see :

cat /proc/asound/cards
 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfc300000 irq 22
 1 [default        ]: USB-Audio - USB Audio CODEC
                      Burr-Brown from TI USB Audio CODEC  at usb-0000:00:1d.1-2, full s

so why alsamixer recognize default audio device as HDA intel and not a USB Audio ?
anyone who has two or more sound cards with the same issue ?

I am using latest Factory but I also do tests on 11.1 and it’s the same

thanks

I don’t have two audio devices. … I note the following wiki:
USB headphones - openSUSE
which suggests:

Initial configuration
To get openSUSE working with USB headphones, it is quite easy.

  • Connect the USB headphones.
  • Select the SuSE menu > Applications tab > System > Administrator Settings (YaST)
  • Select Hardware > Sound

You should see a list of audio cards. Sometimes, it doesn’t list the USB headphones automatically. If not, we can add it manually.

  • Click Add
  • Search for USB audio
  • Select USB Audio, Generic
  • Click Next
  • Leave Quick Automatic Setup selected and click Next

You should now see your sound cards including the USB headset. Now we need the system to prefer the USB headphones, when connected.

  • Select USB Audio
  • Select Other button > Set as the primary card
  • Click Finish

At this point, the USB headphones should be active. You will need to have them connected when the computer starts, or you will need to restart the sound services to make them active.

If the computer is started without the USB headphones, the soundcard will be the active sound device.
Does that shed any light on this?

Again, since I do not have such hardware, I can not offer any information from experience.

Good luck!

thanks for quick reply …
this helps, now is default device 'USB audio"
anyway this is not solution for me :frowning: … when I unplug sound card an type alsamixer I got :

cannot open mixer: No such file or directory,

because /dev/snd/controlC0 didn’t exist … when I plug usb card back, alsamixer works again,

I am just wondering why alsamixer can’t check default device (using e.g /proc/asound/cards) and simple used it as default device :\

anyway thanks …
