I don't see anything in the driver [1] which would indicate that the issue is
in any ways specific to BeagleBone (apart from the beagleaudio strings in the
driver). You are not using the McASP, nor the edma-pcm/davinci-pcm.
What you seams to have is a custom sound card driver for USB. Is there a
reason why you could not use the already available USB sound card for this?

Are you running exactly the same kernel under ubuntu and debian?
