Add another one.  I also have the same issue with the gun sound, after the first shot a gun sound starts and does not stop.  It only happens with the guns and I'm not sure if it is even the Capt Sim Gun sound or a conflict with some other game that uses the same trigger code.

Gun firing starts and stops but the gun sound is constant.  If you switch to missles after they fire and you still hear them in the background of the constant gun sound.  The only way to stop them is to End Flight.

Hopefully someone can debug this or track it to a line in the config.
I also reported it in a ticket.
