For games audio must be live-encoded to AC3 to DTS (there's a hack for Realttek drivers - search for link in the threads).
I know this post was from some time ago, but I am looking to solve my gaming sound problem and as much as I have searched around here for it, I seem to be going in circles. If you wouldn't mind pointing me in the right direction, I would appreciate it.
HTPC (NVidia 780TI) --HDMI--> Vizio P65-C1 --Optical--> Vizio SB-4551
(I have other devices connected to the TV as well - PS4, Xbox 360, Bell receiver) so that's why I am not connecting HTPC optical directly to the Soundbar.
Here is my issue. From Plex, my sound is what it should be - DD5.1, AC3, whatever, but from my games, all are CDDA 2.0. Now after reading the threads and trying EDID route, I finally understood why. Question is:
How do I do that Live-encoding you mentioned above? Do I need other sound hardware? If so, how do I get that sound output going through the NVIDIA HDMI connector going to the TV? Or is this is software live encoding option.
Appreciate any help.
