All this means is that for your specific laptop version, you need a
quirk to be able to properly control the microphone. It's not a big
deal, just determining how to do that is a bit tricky.
I suggest emailing the Linux kernel sound developers at
alsa-dev@xxxxxxxxxxxxxxxx and provide the exact kernel version you are
using (first try the latest release to be sure it's not already fixed),
and any hardware information you can provide as well.
The developers there will probably ask you for more specific things, and
you all can work from there.
Best of luck!
