Comment 110 for bug 192382

Hi,

I also have a ALC861 based integrated sound card:

lspci -vv | grep -i audio
00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC861 Analog [ALC861 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC861 Digital [ALC861 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The sound works ok, but not the mic input. (It can be heard in the speakers but I can not record it, or use it with skype).

I am eager to try:
sudo apt-get install module-assistant
sudo m-a update
sudo m-a prepare
sudo m-a a-i alsa

But in case it breaks the sound all together, I would like to know first how to reverse it if it does. Anyone knows the procedure?

Thanks,

Seb.
