I feel like this was working a week or two ago before this new beta. If use this built-in function, the Windows Settings app says there is no change. Using the right-click menu to change it works correctly. I have a keyboard shortcut to change audio devices but after DF shows a notification, the audio device is still the same. Trying again shows the same message meaning that it knows the previous attempt failed to change the current device.

I attached a short log of trying to change the audio device twice.
