MIC JACK detection fails

Postby Martin25 » 2018-03-06 10:49


I have a problem with detecting microphone on my Lenovo laptop with a combo jack.
When I plug in my headset, the
Code: Select all
utility shows only
Code: Select all
 jack/headphone HEADPHONE plug
and MIC is undetected.

I am sure the mic works fine because it works in Windows.
I found, for me curious, workaround: 1) boot into Windows, 2) restart computer 3) boot into Debian.
This booting into Windows seems to correct something and mic is detected.
However, turning off and on the computer with direct booting into Debian brings up the problem again. ( What is a difference between restart and turning on ? )
The same occurs when I suspend Debian ( Mic becomes undetected )

I attache two outputs from alsa-info for detailed info ( in both cases mic is not plugged in )
1) http://paste.debian.net/1013380/ - obtained right after booting into Debian with the previous Windows boot. ( i.e. mic is recognized upon plugging )
2) http://paste.debian.net/1013381/ - obtained after suspend ( mic is not detected upon plugging )

Code: Select all
diff file1 file2
tells me there are different values for "Power: setting" D0 vs D3 ( have no idea what it means )

Is there any way to make MIC detectable even without booting into Windows?
