Done that. Still no mic.

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

Hi,

I'm having problem getting the microphone to work on the Lenovo X201s, but 
the audio output is working fine.


It's showing up as:

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High 
Definition Audio (rev 06)
 	[00:1b.0 0403: 8086:3b56 (rev 06)]

I've alsa-plugins-1.0.23, alsa-utils-1.0.23, alsa-lib-1.0.23 installed.

alsamixer is showing Capture at 100%, Analog Mic Boost at 40db and Digital 
at 100, but captured using "arecord" or "rec" and then playback is all 
just dead silence!

Any pointers on how to make this work would be very much appreciated.


Thanks,
Jeff
