[2020] The "mute when GW2 is in background" option turns itself on every time you restart the game. This is disastrous in pvp, when you can wait on a queue for 10 minutes then miss it because the sound has turned itself off.

Hey everyone! Just wanted to let you know that we are definitely aware of the problem. A fix will be out soon. :)

There is a special way we can play sounds to bypass this option (such as for the PvP queue pop sound), but it is used in only a handful of places. If it is being used on some random prop in Rata Sum then that's unintended so I'll take a look and see if it is referenced it places it shouldn't be. Thanks for letting me know!
