BF3 on PS3 issues - sound dropping out & lockups

just reporting most likely like thousands of others about the complete sound drop out/silence issues I experience every single time I play BF3 as well as consistent system lock ups on maps like Grand Bazaar & Siene Crossing. Lock ups also seem to occur frequenly in higher ticket % games, not sure if it's a stat tracking thing or not but I do not it is not a local user thing because often after I lock up & will powercycle, log back into the same session to find out several others have locked up as well. Additionally the sound thing.... it happens more & more each day, extraordinarily heavy on maps like Noshar Canals, Damavand Peak & Kharg Island, so frustrating. I love all the new content drops & the like, but this game has been out for over 9 months now, I would appreciate if you would get these issues hammered out. There are other issues as well, but if you could just solve those, I'd be giddy.
