    Audio stops working when passed through surround receiver

    I have my computer hooked up to my home theatre (Pioneer VSX-524-K & Optoma GT 1080Darbee & 5.1 speakers) via HDMI out of my GeForce GTX 1650 4GB.

    When I connect the computer directly to the projector, I get video and audio (the projector itself has a speaker), but when I connect my receiver between them, I get only video. In other words,

    Windows + HDMI + Projector = picture + sound

    Windows + HDMI + Receiver + HDMI + Projector = picture - sound

    The receiver successfully passes surround sound received from my Blu-Ray player.

    Is there a setting somewhere in Windows 10 I need to tweak to get the audio to go through the receiver?

    I would suspect a setting in the receiver. The PC doesn't differentiate HDMI loads. Its outputting the sound and its up to the device that is attached to it to take the audio and do what it needs to do with it.

    Try the exact same connections with a normal HDTV (instead of your projector) to diagnose if it is a receiver setting issue.

    I don't have another HDTV on hand at the moment, but will see if I can get one. How can the display or the receiver be the problem when video and audio both play fine through the receiver from a DVD player? Do you mean the receiver might not know how to handle audio from Windows?

    Full disclosure: I had the same problem with my previous computer (just upgraded), also running Windows 10. Occasionally, I was able to get audio out of that, but it was not consistent, so difficult to troubleshoot. I've never gotten my current computer to output audio through the receiver.

    In addition to the HDTV, I'll try to test with a different receiver.

    Are you using HDMI from the DVD player?

    I still say some issue with the receiver or HDMI Cable. This makes two computers, according to your post with the same or similar problem.

    Yes, HDMI from DVD player. Although the problem appeared with two different computers (which might suggest the computer is not the problem), they both run the same OS, so I supposed the same config problem might exist in both cases. I'll try a couple things and report back. Thanks.

    Good news! I ran tests with six or seven different setups, moving my DVD player and computer between rooms and connecting them alternately to the receiver and directly to the projector. The tests were very confusing, because some cases made it look like the in-wall cabling was the issue, and others made it look like the receiver was at fault. It turns out one of the HDMI inputs on the receiver--the one I've always used for the computer--passes only video, not audio. Fortunately, the receiver has four HDMI inputs, and I need only three, so I just plugged the computer into the other input, and problem solved!

    Thanks, everyone.
