Unable to get VR Headset output UE5 windows

Question

Hi

We are unable to get to audio come from the quest 3 headset for a PC VR windows build using UE5 and 

wwise 2023.1.7.8574

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

The build is for a windows game with the ability to switch to a VR mode

Has any one had any luck with this?

Here is the issue our programmer has sent me 

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
