Porradaman,
That second issue is unrelated to this one, but here’s information on it. Short version - we changed some things about the game client and as an unintended consequence, the ability to mute sounds was temporarily disabled. There are new LUA script options in the latest builds of the game which will allow you to do this again, however, we don’t support this directly in tech. I recommend going to the UI/Macro forums linked above for information on it, and if you need help muting them, you can ask a question on those forums.
