XR Audio Device id?

Unity Engine
1

Is there a way, in the XR API, to get the audio device GUID for the HMD?

For example, Oculus allows the user to pick whether they want to push audio through the HMD or the windows target audio device. If we are using an audio middleware, like FMOD, it needs to know which device to target.

Is there a way to get this through any unity API?

I’m having the same issue - no idea how to get the device GUID for the HMD

We’ve encountered the same issue, with no obvious resolution yet.

When playing audio using audio middleware in the Editor itself, the audio comes through the windows speakers. We desire the audio to come through the HMD itself.
Previously this was done using

OVRManager.audioOutId

And assigning that to the middle ware as output target.

Is there an equivalent in the XR framework? (Unity 2019 LTS)
