Microphone not working on PCI ID 8086:3b56

Microphone not working on PCI ID 8086:3b56

[Jeff Chua]

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

Did you try to play with model option for snd-hda-intel driver?
For example, model=lenovo-x200 ?

Didn't know there's such option. But I'll try it now. Is there an
option to if the driver is not compiled as a module?

Yes, you can pass via a boot option like MODULENAME.OPTIONNAME=xxx,yyy,...
In this case, snd-hda-intel.model=lenovo-x200

Tried, still no mic. Perhaps I'm not using the right driver. Which one
should I enable?

CONFIG_SND_HDA_CODEC_CONEXANT
CONFIG_SND_HDA_CODEC_INTELHDMI
CONFIG_SND_HDA_CODEC_REALTEK


Thanks,
Jeff

When you set CONFIG_SND_DEBUG=y, you'll see a corresponding kernel
message.

Enable all CONFIG_SND_HDA_*.

The "lenovo-x200" model is provided by the above codec.

It's easier to enable all of them. They are small modules.
