Hi,
        How to check if it works in stereo or mono mode? I remember
reading hector's entry on his blog that on account of some wierd
sum/difference problem he had duplicated the + signal across both
outputs so it was actually mono?

Regards,
Karthik

You can check which format / quality is used to record in gnome
sound recorder.  Try to record as Ogg, for example.

Also, you can try to reproduce the problem via aplay.
Record like
	% arecord -Dplughw -fdat -c1 foo.wav
and
	% arecord -Dplughw -fdat foo.wav
Are both correctly recorded?

(On a system with pulseaudio, run with pasuspender such as

	% pasuspender -- arecord ...

They are anyway the same ids, so already there.

Hi,
      Sorry for the confusion. My internal mic does work, but wierdly
not in Gnome Sound recorder. Skype detects it just fine and I am able
to talk without making any changes to the code. So, I guess 8930G and
6935G are same after all.

Thanks and Regards,
Karthik

PS: Please also add the PCI ID's of 6920G (0x1025 0146) and 8920G
(0x1025 0145) under the same quirk. They also use ALC889 chipset with
the same pinconfig.
