I am having the exact same problem. I recently migrated back to PC after many years on the XBOX. I wouldn't know where to find a hack if I wanted one.
I have Win 7, fully updated. All I have on this machine is Skyrim, AMD CCC, and BF4 game installed. I have the Xbox controller 1.2 software for my pad, and that's it. I disable Steam before launching BF4. I am doing selective startup where I manually launch CCC, Steam or Origin.
Before the latest BF4 patch, I had consistent "sound loop crashes" and freezes . Even on the Test Range. The game was virtually unplayable, especially after completing a round and loading the next, if I was lucky enough to connect and finish a round. Regardless, when I didn't freeze and was able to connect, I never had a problem with PB.
Post recent BF4 patch, yesterday I got kicked with the 130827 message, and other than the new BF4 patch and PB update NOTHING has changed.
I followed all the steps listed on that EA forum link. Checked the firewall, checked all the drivers (AMD 13-12), uninstalled and reinstalled PB, etc. No DICE (pun intended).
