No sound (FRUSTRATED) updated from XP to windows 7 64bit

[johnnyjeep]

Looking for some help. I have a optical (for sound) and a HDMI (video card only can output video) going out on my comp to my home receiver. Everthing was working fine on XP but when I upgraded to Windows 7 64bit I lost the sound. I have updated the motherboard drivers and still nothing. The only thing i can see that may be a problem is when i go under Control panel> hardware sound> change system sound> properties it show that the S/PDIF jack info shows rear panel RCA Jack. I have my Optical cable plugged in. I have no idea if this is the problem but i cannot change the jack information. IF anyone has any ideas i would really appreciate it. Thanks.

More specific information on your system hardware would help with this.
It's likely just a simple driver thing (most common issue when upgrading a older system from xp to 7)

motherboard is a nforce 680i and a 8600gts nvidia video card. not sure what other info is needed, the video and sound is going through a Denon avr2311cl receiver.
