UE 4.25 No Audio output on WMR Headset

I’m getting no audio output on my Samsung Odyssey+ WMR headset. Is there any setting I need to adjust?

  1. Audio works fine on a fresh VR template on 4.24. It does not work on a fresh 4.25 VR template.
  2. Toggling the Windows Mixed Reality plugin on/off does not do anything.

If anyone has encountered and fixed this issue or has any suggestions it would be a great help.
