Okay, I set every impassable linedef to block sound, and there's no change when I run the level.

I'm having a little problem here. When I start my level, and fire, it alerts many monsters in other areas (behind doors) which shouldn't be able to hear it. I have no idea what the cause could be, since some doors do block the sound, but others don't, even though their properties are the same. I also tried enabling the "Block Sound" checkbox on the linedef properties, but it didn't work. Any help is appreciated...
