[USB-Audio - Xonar SoundCard, playback] No sound at all

[Ilkka Prusi]

After some testing, aplay -D hw:2,2 samplename works but there seems to be no way to set that in gnome or for other applications?

cat /proc/asound/devices
  1: : sequencer
  2: [ 2- 0]: digital audio playback
  3: [ 2- 0]: digital audio capture

So, in short, even though Gnome panel allows setting the device, it does not allow handling correct /output/ when there are multiple choices? E.g. only optical connected to receiver instead of analog.

After some googling, this is already known bug in pulseaudio?
