Description of Issue
Been struggling for 2 weeks to get the system to properly play back 5.1 from ripped SACDs. Briefly seemed to work after connecting to HT receiver via HDMI instead of Ethernet and messing with a few settings.
Now when I play anything in Roon over HDMI, I get about second of playback followed by a few seconds of low-level white noise, and it keeps repeating like that.
I have power-cycled both the Core and the receiver. I have disconnected and re-connected the HDMI cable. I have toggled exclusive mode. When I connect the Core to the receiver via Ethernet, it plays back 2-channel content properly, but of course downmixes multi source content to 2 channels.
This has been incredibly frustrating. Any assistance would be greatly appreciated.
