Front Mic problem in Fedora 14

After upgrading to Fedora 14 I noticed that the built-in mic in my Dell D620 stopped working, after searching here and there I the problem is between ALSA and Pulseaudio, since alsa will show to capture devices “Mic” & “Front Mic” and Pulseaudio will use Mic as the default instead of Front Mic.

So I used “alsamixer” to set the correct capture source and that worked but after a reboot it was set back to Mic. Then I found about “alsactl” which should store the current setting by doing “alsactl store” but that did not work either since I think pulseaudio does not look into that.

Uninstalling pulseaudio as some people suggested solved the Mic problem but caused many other problems when playing many applications that want to play audio (like flash apps such as youtube and video apps…etc),  this is an ALSA problem that pulseaudio try to solve AFAIK.

The solution that I found was to use “amixer” which can be run from the command line with the parameters to set “Front Mic” as the capture source. Here is the full command for my device:

amixer -c 0 cset numid=6,iface=MIXER,name='Input Source' 1
