Music is a .wav file I created. When the music starts I turn the volume down to a lower level. If I open the cabin door the music jumps back up to a default volume. Is there a way to keeps this lower volume level without having to do a STATE save in the EFB?
Currently you would need to disable the 'Auto Cabin Crew' option on the EFB as, with that option enabled, the crew are setting the music for takeoff, landing etc, including the volume level.
