I am using the Chaintech AV-710 7.1 sound card with the latest Via drivers. I have my Pioneer 816 Receiver. I connected the optical out from the sound to the receiver. I set the sound to 5.1 or even 7.1 channel. I do have 2 front, 2 back, 2 surround, 1 center, speakers. I set my receiver to direct digital, and the sound only seems to only play via the front speakers. Even If I do a speaker test in the Via Panel. I tried switching the receiver to different surrond modes, but still the sound will only play via the front speakers. I am sure the Receivers works, since I have tested with the dvd player via optical input.
Thanks
