Sometimes No Sound with Media Player 9.0

For most files, WMP does fine with sound. But for others, I get no sound. I
have verified that others can hear these files, but I can't. Sorry for
posting on the mac group - couldn't find out for Windoze. (W2000, MP version
9.0)

I uploaded a 171K file "nosound.wmv" alt.binaries.mpeg.videos for anyone to
check it out. I know this had sound at one time, so I'm guessing the problem
is with my WMP.

Binary posting has subject: "a Sample Video with no Sound."

Thanks.
