Comment 50 for bug 195605

Hi Michael,

Thanks for the info. I can't seem to activate the mic doing that. I
keep switching to microphone 2 and all I get is silence. I think
Pulseaudio is the culprit here.

My Vaio is vgn-fw139e if that matters. Everything else works fine
including my internal video camera.

Did you do anything special other than what you mentioned below?

Thanks for your help.
