I'm just gonna hold out for the next patch, unless somehow this is a server-side issue which I really doubt. I've tried basically every fix I could find, and none of them have worked. Going into advanced audio settings and switching the output to my headphones crashed my game twice, and the third time it didn't, but it didn't fix anything.
Even if it's an issue with certain systems, I would posit that the updated sound engine simply needs some fixes. When the stuttering isn't happening, sound effects sound mushy and muffled. I'll hold out for the next patch. Doesn't really matter that much.
