Bug ? Oculus audio weird behaviour

Hello,

I'm facing some behaviors that (I think) should not occur :

1. Whatever audio output I set on windows, audio is going through my oculus (rift cv1) headphone, and not on the audio I set (my normal headphone).

2. On the oculus app, even with headphone's volume set to 0, sound is at maximum volume when I enter playmode.

3. There are two checkboxes on the oculus app for "listen to VR audio through computer" and "listen computer audio through VR", both don't do anything.

I'm using the XR Management plugin, and everything is done via editor, I did not test on a build yet.

Is this intended behavior ? Known bug ? Is there any workaround ?
