Want to build ITX for home theater for gaming only. Tried older PC first, HDMI from PC to Denon x220W, and all I Can get is 7.1 "Multichannel", which is NOT surround sound. Am looking for the avr to say "dolby" or something, NOT multichannel which sucks. Windows 10, Realtek and Nvidia, sound control, Doom Eternal, GTX 660. The game plays fine, it's the sound that is bothering me. HDMI from GPU to AVR. AVR to TV.
Is it the game? Am I doing something wrong? Beats me. Any help would be appreciated.
