For my paticular machine the Lenovo G560
The muted "value 3" under Input Amplifier is the key for activation of internal mic.

The ongoing issue of having to reset this each reboot still remains for me ,however;
Latest poitive results from another g560 tester.
He had sent info to alsa-dev recently;

"I have emailed the alsa-devel mailing list with the hda_analyzer diff and and the output of alsa-info.sh. not sure what they will do, but the hda_analyzer tool's about button said to do that."

However most recently He has replied to the list;

"looks like this has been fixed in newer versions of alsa - i downloaded
this version: http://ftp.kernel.org/pub/linux/kernel/people/tiwai/alsa
/alsa-driver/alsa-driver-20101221.tar.gz and compiled and installed
(./configure; make; make install) and now my mic works all the time,
even after a reboot."

So hopefully this will be functioning soon for those non-programmers like myself !
Thanks to all those unsung heroes of the open-source movement in general and
specifically those working with ALSA.
