For some reason my sound is all messed up now for NO reason. Basically the
sound is poor quality and more importantly the audio seems to have cut out
all the DIALOGUE portion of video files, (MOV, AVI, MPG, etc) as well as
garble or completely eliminate the musicians voices in ALL of my mp3. I have
uninstalled, reinstalled my sound card with new drivers...no results. I
tried another sound card, same results. I tried using the onboard audio
device on my motherboard...no positive results. I have not downloaded
anything malicious or new on to my computer. I have also performed any type
of maintenance check like defrag, etc and there is still no improvement. The
windows Startup sound seems fine upon rebooting, but once I am in Windows
Media Player, iTunes, Quicktime, Realmedia, or any game...the sound quality
has gone to garbage. If anyone can shed some light, then I would appreciate
it.

Thanks
