Comment 21 for bug 701271

This patch fixes the problem switching between built in and jack speaker/mic on my Lenovo G560.

What it doesn't solve is the internal microphone's inability to pick anything up.

I have the 'crack of the day' alsa installed by following this:

In order for the internal microphone to be *any* use at all I need to run hda analyzer and bump up the gain?.

The diff from hda analyzer is:

Without this the internal microphone is completely useless - it looks from this thread like I'm not alone with this problem either. Any chance it could be patched?
