I recently upgraded my VMWare Fusion from 2.x to 3.1 and was running Ubuntu 10.04. I had not problems until the upgrade at which point the sound is not working at all. It was fine in VMWare 2.x. I installed the VMWare Tools but it did not fix it. I would appreciate if someone could throw light on the issue.
Thanks
