OK A FAIRLY NEW VISTA iNSTALL AND EVERYTHING CHESCK OUT OK

But I have a very wierd sound issue...
First of all I have used every driver currently available and it doesn't
change anything...
All updates are done
Vista 32 Bit Ultimate
Not 100% sure of when the problem started (Been busy moving pictures and
files around)

I DO get sounds in Movies, Messenger Live, Games, and Music

I DON'T get sounds in windows destop (Starup, shutdown, Minimize, etc.),
office, internet explorer (You tube for example)

System Sounds are eneabled and everything checks out hardware wise....

ANY Ideas??
