Not sure if the two are connected, but I recently resubbed to 14 and (having never had that problem a few months ago) have encountered crippling audio issues that cause immense crackling and stuttering in both ff14 and any background apps I'm running.

This issue generally starts about five minutes after I start playing or whenever any intense action happens. It doesn't appear to be graphical though because changing my settings up or down has no impact on this.

Additionally, and again, not sure if this is connected... subzone based BGM goes silent moving between different parts of the same zone.

That is to say, if I'm in Camp Dragonhead when I log in, the Camp Dragonhead music starts playing, but if I leave into Coerthas proper all BGM stops entirely until I engage in a fight.
