There is a bug in which all of a sudden some sounds are not working. I have a 5.1 setup so sounds like suit changes, running, and picking up weapons come through the center speaker. All of a sudden some of these sounds stop. Dialog, Nanosuit voice, and shooting still come through, but running, suit power changes, sliding, and others do not.
Usually when a level is loaded the sounds come back. I searched for it and only found 1 other person mentioning it and no dedicated thread. Anyone else having this issue?
