As title says, game audio cuts out randomly. I haven't been able to find any rhyme or reason to it, but it is really annoying in group content. I have to either suffer through the rest of the run with no audio, or have the group wait for me to restart the game.
It's just the game, all other audio on my PC works fine.
I searched around a bit, and looks like others have been facing this problem for quite a while too (a year or more), but I didn't find a report on the forums, so here it is.
