I'm trying to enable the background music on aerofly R/C 9 on an Intel Core i9 2019 MacBook Pro (I have the same issue on R/C 8).
Pressing the M key doesn't do anything like Q for example, which turns on/off the sounds normally.
I checked the folder "/Applications/aerofly RC 9.app/Contents/Resources/music" and the MP3 are there, and playable with a media player.
Has anyone else encountered this?
I tried adding more MP3 files in that folder but nothing changed.
