Hi, I have Dell XPS M1530 laptop with Linux Mint 10 installed. Since the liquorix 2.6.37 update, my microphone stoped working. The mic was ok with liquorix 2.6.36 kernels.

Here is my alsa configuration: www.alsa-project.org/db/?f=deb126d4779e20feb3fafda6742003a4881b7856


Can you help me to restore input sound from mic?

I have the same issue with my Acer Travelmate 4530 AMD QL-64 using Debian/Sid and kernel 2.6.37: no microphone sound input.
Mic working well with liquorix 2.6.36 and previous kernels.

After upgrading to kernel 2.6.37-0.dmz.6 both the external and internal microphones are again working (tested with audacity)

Kukaraja, this is probably a bug in the upstream linux kernel. Google for bug reports that share your device ids with 2.6.37. You can collect the information you need with this script: www.alsa-project.org/alsa-info.sh

Damentz, thanks for the tip.

I found a solution. It's a pulseaudio bug: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/680810

There is a workaround for the problem by modifying /usr/share/pulseaudio/alsa-mixer/paths/analog-input.conf.common,
adding this section (reboot or restart pulseaudio to test):

[Option Input Source:Internal Mic 1]
name = input-microphone
priority = 19
