Thank you very much  for testing...

I do not have hardware to test this.

I'll look into detection code again. I will try to find another detection procedure (as was done for cmi8330).

I do not have such a card. The debug code shows that it comes from
the wss detection procedure. You may check if the azt2320 driver
correctly enables access to the wss codec (it looks like the codec
is not accessible or it is very slowww).

I tested: AZT2316R + CS4231A-KL (card I38-MMSN852)
