Can you double check the volume slider on Youtube's player?

It sounds stupid, but just to get that out of the way.

I am running Vista Pro. When I log onto YouTube and attempt to run a video,
the video runs but I get no audio. I have installed the latest Flash player
version but sitll no luck. YouTube videos that are emailed to me play audio
just fine. The YouTube Help video on YouTube's help site plays audio just
fine as well.

Any ideas?
