hi
I used hda_analyzer to fix my internal microphone on my lenovo G560 laptop. I had to make the following change before the microphone would work:

My alsa version is 1.0.23 (ubuntu 10.10). I've attached the output of alsa-info.sh.
This fix has also helped other G560 owners: https://bugs.launchpad.net/ubuntu/+source/linux-backports-modules-2.6.32/+bu...
If I need to provide anything else, let me know.
