Air to ground ROCKETS do not have their own sound anymore, if you place the camera behind the rocket, or let them fly by, there is no audible sound.
A/G Missiles and Air-to-air missile work fine, but any simple "dumb"-rockets don't.
I am pretty sure it used to work about 2 years ago, but at some point it was missing.
I had mentioned this in the discord bug reports, also in the weapons-bug forum but it did not get through it seems, some people told me it was the supersonic issue with the camera in front of the missile , but i am aware of this.
Attached is a track where i first shoot Air-to-air missile, then an AG missile (sound works fine for these) , and then lastly Rockets , where their sound is missing.
also, if you listen closely in f2-view, the sounds of the rockets seem to be "slaved" to the aircraft, so you hear the wind-sounds of the rockets in f2-view of you aircraft.
(the explosion sound works, it is the in-flight sound i am talking about.)
rocket sound missing.trk
