Comment 81 for bug 275998

Ok, so since upgrading to 8.10 I have no sound from the built-in mic on my XPS m1330. Skype, gnome-sound-recorder et al would just record dead air. This even I was able to get it working. I went to Volume Control -> preferences and enabled Digital Input Source (towards the end, for the Options section). Back in Volume Control -> Options, Digital Input Source was set to Analog inputs. Changing it to Digital Mic 1 has gotten my recording working again. Setting Skype to use Pulse for sound input and output works as well. Sound from the built-in microphone is still somewhat low, but not unusable. In fact, I think it was about the same level as 8.04

After reading through some of the other comments, this makes me think either a) Intrepid defaults to the wrong mic inputs or b) my no audio is a different issue from the extremely low audio reported by other users.
