I've downloaded some add-ons sound files for aircraft with no sound that I have also added on to FSX.
What I've been doing is what you do with aircraft add-on files, put them in the aircraft file of FSX.
I put the sound files in the "sound" folder under the aircraft I want sound for. But it doesn't work in the game and there is still no sound. am I doing something wrong? What about add-on panels as well?
