Can't get DTS-HD-MA, Dolby TrueHD and Atmos on GTX1080 + Onkyo RT993 A/V Receiver
I just made a clean full install of the new 368.81 drivers on my PC with Windows7 64, and the only supported format showing are basically DTS and DD.
I tried to use other inputs on the receiver too (dvb/sat and bluray player) but I'm still getting DTS and DD only.
Bitstreaming is enabled (Confirmed by audio volume adjustable only from the receiver)
I'm using those 2.0 hdmi cables and I'm getting 2160p@60hz no prob:
Atmos and HD audio works if I play movies from the Samsung K8500 UHD Player (I tried Deadpool and The Martian, they got Atmos and DTS-HD MA 7.1 audio), and even the manual of the receiver says it supports HD and Atmos audio formats, still I'm not getting them from the PC via HDMI with GTX 1080 and latest drivers.
How can I solve this? I dunno what else to do.
Those are the screenshots of my audio device supported formats:
*EDIT: I had to delete links to the screenshots as this is my first post so I need 5 to post links.
