Hello !
Sorry for the late respond, I wanted to do some tests before coming back !
It’s really strange because the bug is trigger even if the level has like 4-5 sounds triggered together… (I used the “au.debug.soundwaves 1” and “au.DumpActiveSounds 1” commands to see what sounds are playing)
I tried to duplicate one of the problematic levels and just delete the NavMeshVolume and everything work perfectly, except the actors who are supposed to chase me of course…
I still have the Assertion failed error from the first post when I Alt F4 the standalone game with the bug ongoing but not in the duplicate level.
I also checked my platform Audio settings (for Windows) and I don’t see anything wrong (for me)
Again, thanks for the help, and if I see something else, I’ll add more details !
