I would like you to take a look at this MajMalphunktion when you can Since U11, I'm having sound issus that I didn't had before. I'm now having the background sound/music of some areas following me: Airship background sound, Shop sound, House k music, Clapping combat sound (example, when you have one of those minos near you in the VoN2 maze).
I have these almost on a regular basis, and the only way to fix it, is to close the game and restart it, logging out and back in dosn't work, I've even seen the sound continue in the character selection page two or three times.
Anyone else having sound issues since U11?
