I'm trying to use the SPDIF Coax out to my amp which I had working before I had to move the PC to a different location, but now I can't figure out how to get the passthru working. Usually I get a blue light on the amp for Multichannel decoding, but it aint happening. When I play a dvd thru ZoomPlayer, all I'm getting is 2 channel sound - no Dolby Digital or DTS. What's frustrating is that I had it all working before I moved the PC. I'd appreciate any help. Thanks, David.
