[linux-audio-user] USB Audio Problems

[Mark Williams (MWP)]

Hi all,

Has anyone else been having USB audio device problems with the 2.6.0-test kernels?
I have the ALSA USB audio driver enabled, as well as the normal USB audio device driver (in the USB section).

On plugging on the device i get the output below.
If i then try and use the /dev/dsp device supplied, the app trying to play to it locks up (even a kill -9 wont make it go away).

The USB device is based on the texas instruments PCM2902.

Here is the dmesg dump:
