I am currently working on a mission and have added some custom music to it, but the music can not be heard if the player is inside an armored vehicle, in my case a Panther. When I turn to 3th person camera view the music is hearable again.
This is a bit annoying as it basically ruins the extra immersion I had planned with the custom music. (Panther patrol mission)
Would be nice if you can override the sound proofed interior of armor.
