Are these JVS you are talking about, because last time I checked, JVS doesn't have only one line of events.To remove the sound from the door, get rid of the line that contains any sound file at the end param.
If it was JVS, I would have said JVS, not brick doors.
I don't think there's any events for it so you'd have to manually edit the file.
That was what my confusion was. I assumed you, badger, weren't acquainted with the distinction between a brick and JVS, so I assumed you meant JVS, and not a brick. JVS have events, bricks have coding.
