Sound Recording With Intel High Definition Audio On Dell Latitude D820 & Gentoo
The Dell latitude D820 notebook with the Intel High Definition Audio sound card (snd_hda_intel) has only one jack for microphone and line in inputs. The outcome of this feature was, that only the internal microphone input worked on Linux :)
It was a problem for a longer time, there was a possibility improve — to set the position_fix
option, but it never worked for me.
Fortunately, I found an excellent guideline for Debian, where this problem is solved :) Let’s adopt the instructions for Gentoo.
