My first post so I apologize if this has been beaten like a dead horse.
Running 7 64 bit, motherboard is GIGABYTE GA-870A-UD3
with Realtek ALC 889 sound. I have my HTPC connected to my Onkyo HT-S6100 via HDMI. When I play a BluRay/DVD, I'm able to get DD and DTS no problem. Whenever I try to play something else the only speaker that works is the front center channel.
When I set up my speakers in WMC7 all 6 speakers correctly emit the test sound. However once I play content in MC it's just going through the center speaker.
When I try to configure my speakers in the Realtek HD Audio setup the only speaker that emits a test sound is the center speaker, and it makes a sound regardless of the speaker being tested on the screen.
Anyone have any clues on what I can do to get the 5.1 sound when I'm not using a BluRay/DVD, or at least to get sound out to all the channels?
Thx in advance. I'll be checking back however won't be able to tinker with the system till next week.
