Quest 2 Microphone louder than Quest 3, Fmod+Photon Voice 2

Hi,

we’re using Fmod with Photon Voice 2 on Oculus Quest and I’m running into an issue that I can’t get to the bottom of.
For us microphone on a Quest 2 is way louder than on a Quest 3, also the Quest 2 exhibits heavy feedback where output voice is picked up by the microphone again.

Quest 2 & 3 mics are normally the same volume, this does also not happen using Unity Audio instead of Fmod.
This could very well be a problem in the Photon Voice Fmod integration, but I wanted to ask here in case someone has a pointer in a direction I could investigate.
I didn’t see anything in the logs (with api error logging), tried disabling all AEC, AGC, and Noise supression on the Photon Voice Recorder, Photon Integration code also looked ok when looking over it.
For mic selection I’m using the default device (fmod id 0).
Quest mics have 2 channels maybe that’s something?

Unity 2022.3.51, Fmod 2.02.22, Photon Voice 2 v2.56

I might have found a potential fix, setting the output mode on android from auto (aaudio was the default afaik) to opensl es resolved the issue for me.

Still curious why this was happening.
