VR:Media Player audio in Speakers, not HMD

Whenever we play a video through the Media Player for our intro in VR, the audio for it always defaults to coming out of the speakers instead of the HMD. All other audio comes out of the HMD like normal.

This only happens on Oculus headsets. Vive headsets seem to be ok but Quest 1/2 and Rift(S) have this problem and it’s only on a packaged build.
