Thanks.  Let's cut out bugs step by step.

The probing problem with the latest driver might be fixed by the patch
below.  Could you try it and load without probe_mask option?

Also, what output did you test actually?  Is the output from the
built-in speaker (if any), the output from HP-jack or both?
