I ran
sudo hda-jack-sense-test -c 0 -d 2
but I got an error "ValueError: wrong proc file format ( In-driver Connection:
6)"
This is bug of the codec parser of hda-analyzer
because connection from audio mixer to audio ouput node 0x08 is hidden
select stereo mix as input source is can get signal from mix of DAC and
any input pins

Title:
[G41MT-S2P, VIA VT2020, Pink Mic, Rear] No sound at all
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
The problem is that the microphone is not detected after a reboot. As
a result, some applications cannot get sound from the microphone.
The Input tab of the Sound window lists no device.
I have a workround which is to disconnect and then connect the
microphone after I have logged in.
Interestingly, the audacity application can access the microphone when
the system says that the device does not exist
