Try please attached patch. It disables several unsupported signal paths
inside the codec to help widget parser to manage it. There is actually
two options in a patch:
 1) To disable playback mixer so you will not hear what you are
recording. But this situation is predictable.
 2) To use that mixer for playback. You may get system beeper working,
but it is hard to predict what will happen to recording.

Test please and send me verbose logs from both cases if you can.
