Windows 10: Multichannel audio sent from my computer only received as stereo on AV amp

My Windows 11 workstation has an RTX 3070 GPU, whose HDMI output is connected to a Denon AV amp AVC-X8500H. The Windows Sound settings for this output support multichannel audio but the AV amp treats it as a stereo input even when playing multichannel videos on the computer. All other HDMI inputs on the amp work fine with multichannel audio. What might be limiting the AV amp's computer input to stereo sound?

@ H8 : Not if it's only an audio receiver and not an AV unit. I've got a Denon receiver with no video capabilities.

@Irish : Sounds like you need a simple stereo RCA cable. Will the TV output surround? It may not as was stated before.

So your AV RECEIVER doe not look like the one below ????? Then why have a title "how to get audio from HDTV to av receiver" It should have been just HDTV to Stereo receiver.... A/V means Audio and Video....

Also just because you tv out puts Dolby 5.1 does not mean it will go to a stereo receiver and out put 5.1 digital ,Most TVs with return channel sound are for high end AV Receivers and only out put 2.1 sound (same out put from the TV speakers)
