I don't suppose you've tried the 40Gbps AVPro Edge 4x2 HDMI 8K60 Matrix Switcher? I believe I am trying to address the same concerns you are, but was thinking a 4x2 matrix should be fine. And the 4x2 matrix just happens to be 40Gbps, not 48Gbps, and so maybe it will work? Of course, it would be good to understand what the root cause of your issue is -- please post here when you and AVPro figure it out!I recently added an AVPro Edge 8K 4x4 matrix to the my system. I was using an AVPro Distribution Amplifier before to split the video from the audio from my Strato K, but decided to use a matrix instead to allow other devices to also split their signals. However, I have had significant problems getting the Strato K and matrix to play nice with each other, especially in passing Dolby Atmos and DTS-HD-MA. I do not have this problem with my Apple TV or PS5. Both of those work through the matrix without issue.
I have been on the phone with AVPro and they are perplexed by my issue but doing a deep dive into it.
Nevertheless, I found that putting an AVPro Edge Distribution Amplifier between the Strato K and matrix fixed the problem. It is bizarre to both me and AVPro support, but Strato K > Matrix > Arcam AV40 would not allow Dolby Atmos or DTS-HD-MA. However, Strato K > DA > Matrix > Arcam works perfect for all surround formats.
Now, one more interesting detail... The DA that I am using in the chain is the older 40Gbps one, not the current 48Gbps model (like the one linked a few posts above). When I tried the 48Gbps one in the chain, the same issue with Dolby Atmos and DTS-HD-MA occurred. Something about the older model DA just works for the chain.
All of this to say, my experimenting has narrowed down the problem to something between the Strato K and 48Gbps matrix and DA. Fortunately, AVPro is getting a Strato K in their lab to work with, so I hope they figure it out. But given all the problems people are seeing with Trinnov 8K boards and the Strato K, I am thinking there is something off with the Strato K HDMI.
