[alsa-devel] HDA Analyzer - Dell M4500 Internal Mic

[Tom Burger]

Hi all!

My mic didn't work (Dell M4500) . Using HDA Analyzer I create a
configuration that does work. I read that I could send my working
codec to here. So here it is.

Maybe you can also tell me how te make this change permanent?

Good luck,

Tom
