Your error is in the lines above.  We asked the card for a particular 
buffersize, but the driver returns some garbage instead.  In particular 
the "period_size" of zero is going to mean that we haven't got any 
buffering.  Your driver didn't return any errors about this or it would 
have been printed up.

Try fiddling with a newer version of alsa and see if that helps.
