Type: Object sound pointer, normal
Purpose: Plays the object's death sound, if it has one. If the object uses certain sounds as its death sound, it may play one of a set of random sounds as documented here:
1. If the object uses any of the "podth1", "podth2", or "podth3" sounds, it will play one of the three sounds at random.
2. If the object uses either of the "bgdth1" or "bgdth2" sounds, it will play one of the two sounds at random.
If the object has the BOSS flag in its Bits2 field, it will play its death sound at full volume. This is used by most DOOM and Heretic bosses.
