ok i tested the new build (33.4) on my character thats in the middle of massive packs of zombies. i set an alarm off to see how much stress the sound takes, i heard the alarm, i swung at some zombies i heard that, i heard zombie noises, i heard banging on windows all this happened within the first 5-10 seconds of the alarm sounding off, as the rest of the packs came in the sound of the alarm and zombie noises started to stutter, it didn't give out completely, and after that sounds continued to presist after i got a few in game blocks away from the massive horde of zombies. that's what i'm experiencing, i'm not sure if its happening with everyone else. the new foot step sounds are awesome i'm glad that the sound at least presists even after its been stressed. in build 33.3 it seemed to just cut out and never come back.
