WIndows 11 stops recognizing monitors as audio output devices when idle
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 aud...
1. Check if the cable has any problem. Use another cable to and see if the problem resolves.
2. Check if the output port works fine. If your PC has multiple HDMI output ports, try different ports and see if the problem resolves.
3. Check if the monitor works properly. Make sure the monitor’s speaker volume is not turned down or muted. Then try connecting the monitor to another PC.
Hope this helps,

- I tried using different cables and changing the ports, but it didn't fix it. Also, I think you misunderstand the problem. The monitors work perfectly and as expected from when I turn on the computer and continue to do so as long as I actively use them.
The issue starts after my computer goes idle and turns the monitors off automatically. Half the time I start using my computer the monitors turn on but they aren't recognized as output audio devices in windows until I start the troubleshooter. Once I start troubleshooting windows immediately recognizes them and then I can continue to use them as normal. The monitors are different brands and one uses HDMI and the other DisplayPort so It seems most likely that this is a software issue in Windows rather than a hardware one on my end.
Thank you though!- I have this same problem, initially thought it was my BenQ monitor issue. Bought a Lenovo with integrated speakers recently, behaves the same. I also used the new cables that come with the new monitor, different HDMI port. Very weird issue. For now I got a small bat script I run when this happens:
net stop audiosrv
net stop AudioEndpointBuilder
net start audiosrv
net start AudioEndpointBuilder
Might put these 4 lines in a hook when screen wakes up.- Microsoft should fix this, you have the solution right here.
