Hi list,
I've seen several people having the same problem I'm having on the
lists. However, I couldn't find a solution :-(
Here's the facts:
Just bought a new USB headset [1]. This one uses snd_uaudio. Playback is
great, but recording / mic in doesn't work:
uaudio0: <vendor 0x0d8c C-Media USB Headphone Set, class 0/0, rev
1.10/1.00, addr 3> on uhub0
uaudio0: audio rev 1.00
pcm0: <USB Audio> on uaudio0
pcm0:virtual:dsp1.vr0: record interrupt timeout, channel dead
pcm0:virtual:dsp1.vp0: play interrupt timeout, channel dead
Here are a few debugging information.
