Ubuntu mic on Lenova ThinkCentre

Had trouble getting it to work:

Opened volume control
File : Change Device : 3 Capture: Monitor Source of ALSA PCM on front:0(AD198x Analog) via DMA (PulseAudio Mixer)
On Recording tab adjust Master record volume up

File : Change Device : 0: HDA Itel (Alsa mixer)
Adjust as necessary, now the Recording tab Digital mic level will adjust the recording level

Right click on volume control and Preferences
Select HDA Intel (Alsa mixer)
Select PCM so volume bar will adjust volume


Not sure it this was necessary, but also followed the following post:

sudo gedit /etc/modprobe.d/alsa-base

added at end of file

options snd-hda-intel model=6stack-digout

then reboot.

After that you have to increase volume in MASTER, PCM, FRONT, FRONT MIC , SURROUND (nothing else, otherwise it won't work), and set input source to FRONT MIC, 8ch.
