Multi-Channel, WASAPI and HDMI Problem [Solved]
mojave:
If Direct Sound works, but WASAPI fails occasionally, the issue can be that something is requesting 16-bit audio instead of 24-bit. Try changing the Bitdepth from Automatic to 16-bit Integer for the WASAPI output.
What projector and AVR are being used?

Anthem AVM60
and Sony VPL-VW675ES
WASAPI only fails when the projector is connected, and not always either. One ColdPlay concert almost always seems to work even if the projector is connected. And once that works, all videos work if navigated to from the OSD, but they may fail from standard view.
Thanks for the bit-dept suggestion. Will try that too.

Just spent another 6 hours trying to figure this out. Nothing seems to work for more than a minute. Often, after everything is restarted, everything is ok. Then, seemingly at random, everything is not ok, and the same files that were being played a moment ago, cannot be played via WASAPI.
The client wants to bitstream TrueHD and DTS-HD MA because most of his titles are ATMOS and DTS:X. So we have HDMI bitstreaming turned on. LPCM video files are set for 7.1 upmixing via JRSS. The projector doesn't seem to be a factor any more. The problems persist with or without it. EDID issues are still possible, but they must be a bit exotic; the EDID issues I am used to are when the AVR doesn't appear as a 7.1 device, but rather is only a stereo device.
Completely stumped! :(

You're in an area that I don't know much at all, but I had a problem like that when I bought a new 4K TV and a 4K stand-alone disc player. It would play briefly in 4K and then fall back.
I tried a lot of things. If I hooked the disc player up to the TV, it worked fine. I read some about HDCP and it requires a complete path. Every device (and cable) must support the _right_level_ of HDCP. I ended up buying a new receiver and then it worked.
If you haven't done it, hook up the components directly to the displays and see if everything works.
I'd also simplify the setup.
Not worth much probably, but at least I've unburdened my heart. ;)

Thanks, Jim.
We tried something like that today, and simplified things a lot. The video plays fine, it's the audio that brings up the error message it seems. We updated display drivers as well. Lots of my customers have 4K displays, and even multiple ones, but this has been crazy. I need a break for a couple of days before I delve back into all this.
Connecting to a display directly is not going to be of much help - we need to get bitstreamed sound to the receiver, and that's where the system seems to be failing.
