View Full Version : [ubuntu] Working Mic stopped

My mic stopped working abruptly.

The problem started (I think) after I installed skype 2.1 beta. Initially whenever I started skype the capture and amp levels would goto zero, rendering the mic mute. This would fix on raising the corresponding bars.

Then at some point the bars stopped moving via gnome-volume-control. I could move it using alsamixer but now that doesn't help revive the mic (both internal and external mic; both worked earlier).

Sound works fine.

I read through

but it didn't help.


Some information I collected using the scripts in the aforementioned wiki
