This has been going on since Windows 10. No matter what I do something changes the defaults to my monitor audio. Its even worse for me because i have three monitors with audio. I just want to use my RME Audio Device and WIN10/11 always at some point changes audio without me making the change.
Just another reason why I hate Windows 11. This is the worst OS since Windows ME and Windows 8. For me Win 11 is the top when it comes to having to reinstall. No other OS was as bad as this.
