Hey guys, Got a weird issue that's absolutely stumped me. I've got a HTPC that's going HDMI into my amp. A few weeks ago, sound just suddenly stopped working (Amp is an Onkyo NR 636). I get video, but no audio. Suspect it may have coincided with the creator's update, but not sure. Windows detects the amp just fine, and the meter is moving when audio is playing. I can set up multi channel audio and all that as expected. A few things I've tried which make it even more weird. Originally it was using the onboard Intel HD video card. 1. Swapped to a 7970 with DP -> HDMI adapter 2. Reset the PC using windows tool 3. Plugging it straight into the TV works fine with audio (stereo only as expected). What the hell is going on?!
