Description Andriy Baranskyy 2009-12-13 23:22:34 UTC

Hi everyone, I am getting a weird problem with the upgrade to kernel 2.6.32.

Under 2.6.31, my external mic was working fine and specifically 'mic' column showed up in alsamixer. After the upgrade, I receive no audio from my mic and mic column has disappeared. Any ideas?

My sound-card is Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) and all alsa intel hda modules in the kernel are enabled (they are the same for both kernels).

I will attach my kernel .config file as a seperate attachment.

Reproducible: Always

Comment 2 Andriy Baranskyy 2009-12-14 02:39:50 UTC

I fixed the issue by writing
options snd_hda_intel model=3stack
in /etc/modprobe.d/alsa.conf
I am therefore closing the bug.
