This is a script issue, and should be posted in the Script's section.

You can either use the "settargetname=x" and "activatetarget=x" commands in the camera script. When it gets destroyed, it can activate the sound trigger and have it destroy. OR you can set a global variable to a value of X, and if the camera is destroyed, the sound script checks that variable in a loop state and can be stopped if that value is reached.
If the camera is the main script and controls the sound and lights, then it can also stop the sound once it is destroyed if a sound is either attached to the camera properties and referenced in the script using "sound=$0" or "sound=$1".
