Anyone who may know, thank you...I have tried everything. Also besides the onboard AC97 SoundChip I have a Sound Blaster Live! Driver are loaded correctly..But at the MOMMENT I'm using the AC97 onboard..
It sounds like you're missing a sound codec...

Is the sound working in VLC?
What kind of movie files are giving you trouble?It's my DVD/Combo (2cd drive E:) that will not play movies, even thru VLC, Nero7(came w/drives) has 2 audio codecs that show up on a check..MPEG2 or MPEG4..I'm still learning about .mp3, .jpeg, .mpeg1-4, .jpg and all others...THANKS for any Help! Well VLC uses its own internal codecs so it's probably not a codec issue then.
Go to Device manager.
(Right click "my computer", select properties, select the "hardware" tab, select "Device manager")

Double click where it says "DVD/CD-ROM Drives" and double click your DVD drive.
Select the "properties" tab.
Make sure "Enable digital CD audio..." is checked and that the "CD player VOLUME" SLIDER is set to high.
Okay so the setting for "enable digital sound " should be enabled, I did not know that....Thanks for the Info DP.So is your problem solved then?Wait a minute... are you now saying that the sound plays fine in VLC?Quote

I was told I did not need the 3-4 pim gray wire that runs from IDE Drive to MoBo or Card. I never hooked it ip..
