I posted on the LTT forum already but I’ll post here to since this a particularly difficult issue. I plan to be running my TV at 4k-120 after I get my new GPU and TV. My receiver only supports HDMI 2.0, so my main HDMI connection has to go straight to the TV. But I would really like to keep using my current receiver for my 5.1 channel audio setup. Anyone have a good solution for this?
Current options I can think of:
Run an extra HDMI cable to my AVR and extend the display so I can send audio to it.
-This seems to break HDCP 2.2 support.
-Having an unconnected screen is really annoying.
–If anyone else goes this route this program can automatically lock your mouse cursor to the primary screen. http://dualmonitortool.sourceforge.net/index.html
Use Gen 1 ARC to send Dolby Atmos to my AVR
-Audio has bad latency and is buggy. (Tested on my 2017 TV. It might work better on the CX)
SP/DIF output on the TV.
-Not sure if the TV can convert PCM to dolby digital for me or not.
-Also not ideal due to low audio quality.
USB to HDMI audio converter
-Haven’t been able to find a good one yet.
-It would need to present itself to Windows as pure audio device. So a device like that might not exist.
Analog Outs on the Motherboard.
-Could work… but my receiver doesn’t support analog in for anything other than stereo.
One more thing about this windows installation is it’s running as a VM on unRAID. But that shouldn’t really matter
