Losing sound after wake up!

[simplemind]

Not sure if this is the right place to post, but here goes.

I have Vista 64, etc. I notice at times when it resumes from SLEEP mode, there is no sound.

Once I re-boot, the sound is back.

How would I diagnose the problem?

Thanks for the link, however, interestingly, when I try to go thru the MS update or hotfix, I click on the V64 button and I get a response " your system does not qualify for this update" .
Still have the problem.
