Try writing to the appropriate /dev/usb?/?/ep?data.

It may be the case that the audio device isn't initialized properly becau=
se the
speed isn't set.  I've no idea what you have to do to get it set.

Anyway, if data gets consumed by /dev/usb?/?/ep?data, but no sounds happe=
n,
then you may have to find out how to program the mixer or the selector.
You could time a
	cp pcm-file /dev/usb?/?/ep?data
to measure the data rate and verify whether the setting is 44100 or 48000=
.

(I'm just telling you what I did in the past to debug these devices).
