Multi-Channel, WASAPI and HDMI Problem [Solved]
JimH:
Congratulations.
RoderickGI:
Well done Fitbrit.
I look forward to reading what the problem was.
fitbrit:
As promised.
The setup was an HTPC with dual HDMI (integrated) outputs. There are also two 4K TVs, a 4K projector and a 4K Anthem receiver.
As a result of the issues, the owner settled on this configuration:
HTPC HDMI1-> 4K TV 1
HTPC HDMI 2 -> AVM 60 -> HDMI output 1 -> 4K Projector
AVM 60 -> HDMI output 2 -> 4K TV 2
We never really figured out the issue, but finally installed an HDFury Vertex device, which is the top of the line. I had previously read that the HDFury Integral had an "HTPC mode" specifically designed for this type of application, so I recommended that product at first. The owner tried that and the Vertex too, but he was either guessing or having trouble installing the GUI.
Once the GUI was correctly installed, I took a look, and we had a stab at figuring out what was going on, but not too systematically. Eventually, while reading the manual on another hunch, I found a section of the Vertex GUI that had the HTPC mode checkbox. We checked that, restarted the HTPC and suddenly it all worked out.
The less expensive Integral has the same feature so could have solved the issue too, but the owner was content not to touch anything now that it was all working. It's not completely optimised, but it is entirely robust, and hasn't failed at all since we got it right. That is in contrast to all those other times when it might work for one or two videos and then fail. We are currently only sending out 1080p, and upscaling in the TVs or projector. This works out well, as most content the owner has is 1080p, and the lack of upscaling in MadVR makes using ROHQ possible, even with integrated video. Because of the ATMOS capabilities of the receiver, we are simply bitstreaming everything for video, although there is a JRSS 7.1 zone installed too.
So there you have it. A bit of a mystery, but a piece of kit designed to solve the mystery solved the mystery.

Thanks for filling us in.
I had a look at the HDFury Vertex specs, and it is an impressive bit of kit.
Where did you install it in the HDMI chain? Just after the HTPC HDMI outputs, before 4K TV 1 and the AVM 60? That is the obvious spot, since it supports two 4K channels with HDCP 2.2.

Between HTPC and receiver. The issue was definitely between those components, since everything worked (and continued to do so) from other sources before the HTPC was introduced.
