Okay, its good to learn something new on every day. So how do I configure McBSP port clocking? I'm very new on these things and was unable to find any useful link on this point. :(
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?
