Have a Dell Optiplex GX270 that when playing video clips in media player 9, the volume is low and you have to turn the speakers up wide open just to hear the clip. Music plays normally in media player. CD's play normally. The normal windows sounds are normal. Just seems to be any video clips it plays. Th pc has the built in SoundMax integrated audio if that helps. I loaded the latest drivers as well.

We have an identical pc in another office and this one has no issues at all. Plays perfectly.

Any ideas???
