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
