I installed the Ubuntu 12.04 on my HP 625 laptop - it's great, but... I still can't use my internal microphone. When I go to Sound Settings it seems like the alsa plugin detects it, but doesn't register any sound.

Any ideas?

Installing Pulse audio volume control from USC and fiddling with its settings got my mic working.

In terminal run:

gksudo gedit /etc/modprobe.d/alsa-base.conf

Add these two lines to the end of alsa-base.conf :

alias snd-card-0 snd-hda-intel

options snd-hda-intel model=auto

Save and reboot.

I tried installing Pulse Audio with no success but it seems to have started working after installing Banshee - I can't be sure that was what fixed it but its worth a try.
