The partial answer is YES. I got this far.
Apple has a built in macOS feature called airplay. If both your pc & your avr have the feature, it will/should work.
This is what I figured out.
To start, familiarize yourself with the menu bar item on the top right near the date & time. Apple says:
To view Control Center, click the Control Center icon in the menu bar.
Next, open the site on your browser
Then open Control Center
In the drop down menu in the Sound dialog box select the Audio icon on the right hand side
On the drop down will appear sources for your audio output
Select your avr
Move your pointer out of Control Center box & it will close.
That's as far as I got. No audio out of the Denon avr even though the screen said airplay.
