Re: Digital Microphones (DMICS) on Intel HD AudiowithSigmatel Codecs

I see what the problem is.  The documentation doesn't show the digital mic on the widget diagram for the 9202, and I haven't had any requests for it on the 9250 series (what this code was originally written for).  The issue is that for some codecs, there is no digital mic port, so trying to configure a nonexistent port would cause the driver to fail.

I'll get a patch worked up and send it to you as soon as possible.
