Photon Voice 2 - Quest 2 Speaker/Headphones

I have a working configuration with the latest of everything (Pun Voice 2.24, Unity 2020.3.2f1, Oculus 25.0), Windows to Windows works great, but as soon as I use Quest 1 or 2 I have the problem that I cannot have sound coming through the earphones plugged into the device, no matter what I do it comes through the built-in speaker.

The issue is also seen with PUN Voice 2.23.1, Unity 2019.4.22f1, Oculus 23.1.

All other sounds come through the earphones perfectly before the app starts, so the earphones work. The fact that it occurs on both Quest 1 and 2 appears to rule out the device.

This all worked in Pun Voice 1. Note this is with remote and local avatars (not Oculus), and as already mentioned it all works apart from where the sound comes from on the Oculus headsets.

It is also noticeable that once the app starts you can't change the volume with the switch under the Quest device, again this worked with Photon Voice 1.

Logcat shows a number of errors summarised below, I have the complete logcat with Log Levels set to INFO if required
