Output to headset PC VR

Question

Hi,

Using 2023.1.7.8574  with UE5 we are testing a pc vr build of our project, I am unable to get audio to use the oculus headset. 

So far the only way to get headset audio is to manually select it as system audio device from windows task bar

Has anyone had any luck with this? 

Here is what our programmer found - 

Enabling the headset audio device doesn't work
because
IHeadMountedDisplayModule::Get().GetAudioOutputDevice() returns an empty string
because
the internal metaxr functions return -1002
Which happens because it's too early because FOculusXRHMD::InitializeSession() hasn't been called yet
