Tried just about everything, still no mic. Sounds works in all cases.


I found that with SND_HDA_CODEC_INTELHDMI selected, SND_DYNAMIC_MINORS 
will be enabled by default which won't work in my case as I'm not using 
udev. Here's a patch to take away the default so non-udev will still 
works.

Do I really need udev to get mic to work?

Thanks,
Jeff
