I had other problems with my CentOs VMWare WOrkstation host environment. I have a Logitek USB headset, which I use with Skype in my VM client running Windows XP.
However, a while ago the microphone stopped working - all I got from it was a load crackling noise. I tried buying a new headset, but that was the same - it seems to be a reaction between CentOs and VMWare.
