For some reason, Windows 11 stops recognizing my two external monitors as audio output devices when I leave my desktop idle. I also have headphones plugged in and they will become the only output audio option even if the audio was set to one of the monitors before.
My power options have my desktop set to never sleep but it will turn the display off after 15 minutes. Half of the time I start using my computer after the monitors turn off this issue happens. To fix this I have to start troubleshooting output devices and then windows will suddenly recognize them again and everything goes back to normal. It's been getting annoying to have to go into settings every time I want to hear audio after leaving my computer.

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.

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

I've tried all of the suggestions above including restarting audiosrv/AudioEndpointBuilder services, power cycling the TV, running Windows audio troubleshooter... nothing worked. No pending Windows updates, no driver updates available. I knew rebooting the PC always fixes the issue, but it's obnoxious as hell doing that every time Windows stops detecting an audio device, which seems to be constantly these days...
Well, turns out putting the PC to sleep and waking it back up seems to work just as well, no need to close down programs or save your work.

I just changed the driver from Nvidia's one to Microsoft High Defination Audio Device driver and it started working.
