So, I ran out and grabbed the new Raspberry PI 4 when they came into stock at Microcenter to enable 4k HEVC content on my 4k TV. In the process of setting it up I ran into an issue. Apparently my receiver, even though it will output 4k, will not allow a 4k input. If I plug the RPi directly into the TV the 4k works great but the ARC only support PCM PII so I lose my surround.
So, the question: would it be possible to have the PI push the video through one HDMI port (maintaining 4kp60) to the TV directly and the audio through the other port directly to the receiver?
