Also having Audio issues on this end too. After a certain point, I will lose all sounds other than Music and System sounds (like limit break filling up, or the victory fanfare when winning an item for instance). These remaining sounds will also frequently stutter. The only way to resolve this is to restart my game (which given current Queue circumstances, is less than ideal).

I've not been able to pinpoint any specific trigger. The only constant I have is that this has only occurred when I've played Reaper, and always in combat.
