We all know how many random issues BF2142 is having. Right now I am expiriencing some odd sounds from BF2142. Whenever I am driving of flying a vehicle I get this random ticking sound as if its trying to make a clear sound but its coming out all screwed up and its this annoying "tick...tick....tick...tick..." sound. This only happens in BF2142, I changed my hardware settings to MEDIUM for sound but still same result, and it sounds even crappier which bugs me even more. If I am going to be forced to turn off EAX and use some shitty Software sound, then forget it.
UAV maybe?
Thats you proximity detection dude, it lets you know another ship or vehicle is near
