would fight for a source and you'd get a horrible distorted sound that was each of the two sounds interleaved * Changed the default of s_alPrecache to 1 -- having it off seems to cause problems for some and it doesn't actually improve things much * Changed a few of the variable names in snd_openal.c to be more sane
