I have changed some setting in flash Player Settings Manager, I don't think it would affect it after all the cam is still working it's the microphone that freezes up, but thought I would tell you this, info is good.

Changing settings on pulse audio should bring up the sound on your mic.

here's my current config

Update:

I found the permanent fix. Changing the Input Device values under gstreamer-properties did the trick for me.

I had a similar problem that was appearing with two different ics (integrated on webcam and old-fashioned analog mic).

It went away after I clicked a few times on the button "Lock channels together" and moved the Left and Right radio-control independently on the Volume Control window, under the Input Devices tab.
