Nope I don't plan to become some kind of kernel developer. I just want to use
my notebook without any issues and want to help others who want to use this
device with Linux too. I just followed Mario's suggestions. I thought it would
be easier for everyone when I create a patch, try if it works and then submit
it to a bugtracker to get the bug fixed.

Please feel free to create a patch based on mine, when it's easier and faster
that way. I don't really care as long as the microphone is working in one of
the next kernel releases.
Thanks for your help Thorsten. I really enjoyed your Heise Kernel-Log series
and I really miss those series. Was always a pleasure to read that.
Kind regards
Markus
