bulk assinging windows-related vr bugs to myself.

This issue appears specific to using the Oculus Rift backend (OVR) where applications are responsible for selecting the right audio device, renaming accordingly.

I tested with SteamVR which offers automatic audio device switching through SteamVR > Settings > Audio. That works as expected using Chrome.

Tested as follows:

- SteamVR audio settings: "When SteamVR is active": VIVE, "When SteamVR is exited": speaker

- Shut down SteamVR

- Launch Chrome

- do non-VR audio playback, i.e. a YouTube video, to confirm that audio plays through the non-HMD speaker output

- open a WebXR page

- audio redirects to the HMD's headphones

That's as expected for SteamVR, with no special handling needed inside Chrome.

Leaving the issue open for OVR backend specific followups.

FYI, it should be possible to use the Oculus Rift through SteamVR to take advantage of its automatic audio switching. That's a bit clunky, but is a potential workaround for this issue until there's a code-level solution.

Removing Internals>VR component and assigning to Internals>XR

I see a setting in the Oculus app to Mirror VR audio, playing to both the default audio device and the Rift headphones.

We may still want to direct audio for Chrome specifically when this setting isn't enabled, but this setting may allow us to lower the priority of this.

Web pages could redirect audio themselves if they knew which output device was preferred.

However, we could effectively make it seem like the default audio device has changed while a headset is presenting.
