Windows Vista DVD Audio in Vista

I am running Vista Home Premium and cannot hear the audio when playing a DVD in Windows Media Center. Does anyone know what is wrong?

MSI K9N Diamond v1.1 Bios v1.0
AMD Athlon 64 X2 4200+ 65W AM2 Windsor
Thermaltake Armor Jr. ATX Chassis & TR-2 550W PSU
2 x 1GB Kingston DDR2 667 Dual Channel
WD SATA2 80/250/120GB/Floppy
Lite-On 20X DVD-RW w/lightscribe
Lite-On 52X CD-RW/16X DVD-rom
EVGA e-GeForce 7600GT 256MB
Logitech® X-230 speakers (2.1)
OS Vista Home Premium

 

What audio card are you using? Is it the onboard? If so what chipset? Realtek has some updated drivers for vista on their site, that work well. Make sure you don't have it surround mode. Also make sure you don't have the audio muted for Media Center. The new volume control lets you mute applications instead of devices.

 

My MSI Diamond mainboard has a built in Creative Sound Blaster Audigy SE soundcard. Audio is enabled in Bios. nForce 590 SLi.

 

I went into Vista Windows Media Center and setup the audio. Now it works....

Thanks.
