Has anyone figured out how to permanently fix the sound-bug? Raising the priority stops it but it also makes the game randomly freeze and stutter... Wasn't the patch for this?

apparently not. Hopefully the next patch will address this.

I can't use the increased priority fix because my system isn't powerfull enough to steal additional resources from the OS. Keyboard input becomes so laggy I end up running past enemies and npc's for 10 seconds after I release the key!
