My problem is my HTPC only outputs 2 channel PCM to my AVR when playing games. My setup is:
PC with AMD Radeon R9 380
Yamaha RX-V765 7.2 AVR
7.1 speakers and Subwoofer
Epson 6100 projector
GPU HDMI is out to AVR which then outputs via HDMI to projector
Under Device Manager my output option is listed as AMD Epson.
I have configured that option to 7.1 and each speaker and the sub test fine in the Config tab. Also each speaker is set to small. Available Codecs under AMD Epson show all the current Dolby and DTS flavors available.
My guess is that somehow the PC is only seeing my projector thru the HDMI chain, not the AVR and is setting PCM output to two channels accordingly, seeing as how the projector outputs in stereo. Bluray disks and games on my Sony PS3 play multi-channel just fine. I am stumped on how to fix it.
