Try writing to the appropriate /dev/usb?/?/ep?data.
It may be the case that the audio device isn't initialized properly because 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 happen,
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).
