Sound quality loss when changing views

Example here:

On switching from one view then back to the original there seems to be a sound quality loss with certain events that I have created. The program is X-Plane 11 and I use FMOD 1.8 (the only supported version for now)

My export settings are Stereo with vorbis encoding at 100% quality, but I’ve tried other settings to no avail. Is there something I might be doing wrong? TIA

It sounds like there’s some phasing going on - perhaps some events are being doubled up or there are too many listeners in the game world. I would recommend asking the X-Plane developers for assistance in tracking this bug down.
