Acoustics on device with Meta Audio SDK

Has anybody gotten acoustics to work with the latest Meta Audio SDK (v56.0) on device? I've followed the configuration guide carefully and things work on Windows in the editor, but in a build on Quest 2 or Quest pro, the reverb produces a crackling sound (just the reverb, not the spatialization). I've played with all kinds of setting, tuning gain, volume, room properties etc. and nothing seems to help.

Any help/pointers are appreciated.

Solved: The issue was related to having another audio source in the scene that was not using the meta spatializer component but was still running through the main acoustics mixer - removing that audio source solved the problem and acoustics are now working fine.

Hi, good work on getting this working. did you have any trouble with the acoustic map. I'm finding that I keep getting the following errors.
