Multi-Channel, WASAPI and HDMI Problem [Solved]
fitbrit:
Some progress.
- Anthem receiver always shows up correctly as a 7.1-capable device in Windows, so it's not a straight EDID issue.
- Decoding TrueHD and DTS-HD MA to direct sound and using JRSS to produce a 7.1 output works fine.
- Using WASAPI with these video-based audio formats FAILS, and I get the message to try 2-channel
- Using WASAPI with stereo files and upmixing to 7.1 works perfectly.
- Bitstreaming the audio from the video files doesn't work, even though Windows believes the AVR is capable of decoding the sound from any of the formats in question.
So what would cause WASAPI exclusive to fail on for video files and the LPCM, TrueHD, DTS-HDMA etc. formats but not 2-channel audio.
Sounds like an HDCP issue, no? But someone mentioned earlier that there would be no video if that were the case.

Can you be certain that the problem isn't related to the files you're testing with? Or how they were made?

Absolutely certain. In part, that's because the files have worked as expected at some point, but inconsistently. One minute they work, and the next they do not.

I had a look at the specs of some of the equipment you are connecting up. Quite a setup.
I still think you have an HDMI Chain or Endpoint issue, but it may be HDCP that is preventing the audio getting through. If the source device decides that the HDMI Endpoint or any part of the chain isn't HDCP 2.2 compliant (for 4K content) then the source will take some action. I have read of HDCP issues including Video/No Audio, Audio/No Video. neither Audio or Video, a display of the message "Unauthorized HDCP". I think the response is dependent on the source.
It is a pity that you weren't involved in the HD Fury Integral setup and testing. That looks like some piece of equipment that should solve any issue.... but, it is limited to one and only one HDCP 2.2 output, while the other is HDCP 1.4. 4K content requires HDCP 2.2. There are also a bunch of other settings that need to be set right as well.
I could not think of one place in the HDMI chain that I could install the HD Fury Integral and supply HDCP 2.2 signals to all sinks. You have four sinks in that setup, three 4K TVs and one 4K projector. You also have two sources on the HTPC. Do they come from one discrete video card, or are you using one from a discrete video card and one from an iGPU in the processor?
In the configuration you described;

HTPC via HDMI to a 4K TV.
HTPC via second HDMI to an AVR (20ft away), which in turn is connected to the 4K TV and another 4K TV via a splitter, and a 4K projector via secondary HDMI output.

So;
HTPC -> iGPU HDMI port -> 4K TV
HTPC -> Discrete Video card HDMI port -> Anthem AVM60 HDMI Input -> Anthem AVM60 HDMI Output -> Sony VPL-VW675ES Projector
Anthem AVM60 HDMI Output -> HDMI Splitter -> 4K TV
-> HDMI Splitter -> 4K TV
Are both HTPC HDMI ports HDCP 2.2 compliant?
Are the TVs all HDCP 2.2 compliant?
Is the splitter HDCP 2.2 compliant?
The Anthem AVM60 seems to be HDCP 2.2 compliant all around, but I couldn't find anywhere that it specifically says both HDMI outputs are compliant. It just says it has HDCP 2.2 and two parallel outputs. But one includes ARC (Audio Return Channel) and the other doesn't, so there may be a difference.
The Sony VPL-VW675ES is HDCP 2.2 compliant but doesn't include Audio. I wonder if that is communicated back to the source, which then mutes the audio? If so the best I could think of was to put the HD Fury Integral between the Anthem AVM60 and the Sony VPL-VW675ES, as long as both outputs on the Anthem AVM60 are HDCP 2.2 compliant.
So I think you need to methodically work through the HDMI chain and confirm everything is HDCP 2.2 compliant. The variable results you are seeing may be as a result of what is seen as the HDMI Endpoint, which probably depends on what is turned on when the HTPC is turned on, or what was last played to, or all sorts of stuff.
As always, Good Luck! ;D

Thanks for your very well thought-out reply, Roderick. After another 5 hours of working with my client and many more hours of reading, the issue is fixed.
Your evaluation of the setup was not quite accurate, but since I am now exhausted, I will provide the details during daylight. In the end the HDFury Vertex came to the rescue, but the feature I used is part of the Integral as well.
This was a huge stress on my mind for the past week. I can finally enjoy what’s left of my time off, I think.
