Microphone not working at all.

Here is the link with alsa information of my PC:

Have tried alsamixer, pavucontrol - no way.

remove model=generic in/etc/modprobe.d/alsa-base.conf

Modprobe options (Sound related)
!!--------------------------------

snd-hda-intel: model=generic

[Aurel Branzeanu (thunder-riscom)]

Removing doesn't make the microphone work. In fact, I have inserted this string trying everything possible to enable the mic.

do you mean both rear and front mic does not work ?

it is strange that pin-ctl of front and rear mic are different

you can try hda-analyzer to change vref of the rear mic

does the line in work or not ?

Rear mic doesn't work. The front mic is not connected from the motherboard. Don't know if line-in is working.

Tried to change vref on rear mic - it didn't work on any setting.

seem many gigabyte motherboards are using same pci ssid 1458:a002

the driver apply another gigabyte motherboard 's alc889 CD pin fixup

which gigabyte motherboard do your have ?

does it have the internal CD connector or AUX input?

did your hear any signal from the lineout or headphone if you unmute "rear mic playback switch" and rear mic playback volume ?

how about alt_capture device hw:0,2 using MIX adc 0x09 instead of Line adc 0x08 ?
