Guild Wars 2

When I fist visited the city, I came across Uzolan’s Mechanical Orchestra and thought the music was cool and a bit eerie. A few weeks later I told a friend who just started playing about it and I took him there to show him. But the music no longer plays. The animations of the drums and instruments are there, but no sound. The NPCs continue to talk about playing music, but nothing. I hear music elsewhere, just not there. Neither did he. Where did it go?

For some weeks I noticed this too, no changes in system made by me, all sounds work, just the music is gone.
Odd this has been posted 2-3 months ago without any answer ( like many things reported )
Makes me wonder if there is a quicker way to report these things and I am the only one adding things here :-)

works fine for me
