raze/source/exhumed/src/sound.cpp
Christoph Oelckers 43f899f2ce - Do not start multiple instances of the same sound on the same source in Exhumed. 
From the looks of it the engine calls the sound function repeatedly while the sound plays to perform distance checks.
With the OpenAL backend these checks are totally unnecessary and shouldn't do anything.
