After the 1.3 patch problems with sound EA has released this updated version to correct most sound issues and other small bugs.
Network/Server Fixes
We fixed a crash in co-op mode when restarting the map – this crash was known to occur right after a map switch
We removed the default Remote Admin Password for servers – there was a default password in place that could be used as an exploit
We changed the object collision system to prevent exploits involving players hiding inside of objects – more widely known as the "Coral Sea" bug
Client Fixes
We locked out an exploit to prevent users from seeing through walls.
Sound Fixes
We modified several attributes of the sound system to provide better sound performance. If you still experience problems, be sure to consult our guide below.
