Google Chrome No sound!!

Hi!

Last night the sound on google Chrome completely stopped working, the sound on my PC works (skype, IE, games etc) but nothing what so every in Google Chrome.

What I have tried:

Unistalling sound drivers (two times) - Then reinstalling
Uninstalling Google Chrome (two times) - Then reinstalling
Uninstalling Flash - Then reinstalling (I later on found out that Chrome of course has flash already installed inthe browser so I automaticly eliminated this as a problem)

(Of course I have tried rebooting as well)

Windows 7 64bit (Ultimate)
Google Chrome version 21

Any help is much appreciated.
