Audio Volume Crash on Quest?

Hello,

We are seeing a Oculus Quest only crash on 4.22.2. I’m not 100% sure it is FMOD related, the audio engine we are using, but I thought I would see if this has been encountered by anyone else using FMOD in these forums.

It seems to happen only when an Audio Volume is used in a level, on the Quest.

It doesn’t sound familiar and I cannot see anything related to FMOD in the callstack. I would try the Unreal Engine forums if you haven’t already.

Yeah, this post was just a long shot to see if anyone has ever encountered this before. I’m still waiting on a response from Epic.
