Same issue here. Started right after Windows 11 update. Windows wont detect my Asus monitor as an audio device anymore, which is really a pain dealing with 2 computers on the same monitor. I dont want to change my audio jack everytime I swap between cpus.
sanjunipero's solution doesn't work, it gives me an "access denied"... Dont know why.

    I'm also getting the access denied 😕 So I figured try run it as admin and it worked, still no audio on my monitor though even though it's working fine through surround sound

    Same issue with Windows 11, although I was already on Windows 11 before I got rid of my speakers and went to the TV (monitor) speakers, so I don't know if it was (would have been) an issue in Windows 10. I also note that, while the TV is turned off with no activity, Windows 11 will not turn my TV back on when coming out of sleep. I have to use the power button on my remote. I think this is a problem with my TV (Samsung UN40JU6700).

     

    I only see the problem maybe 1 out of 20 times coming out of sleep, however. But there is no rhyme or reason to when it happens - just appears to be random. To date I just end up resetting my computer (since it happens infrequently). I would very much like to see Microsoft fix this issue.
