Guild Wars 2

This happened on and off starting around the April Fools update, but now it is consistent. I have the World 1 Super Boombox , and now it does nothing but stop all sound and play nothing but sound effects when I click 1-5. I miss the music of the SAB, and do with I could use this music instrument again. I was wondering if anyone was aware of this, and if the World 2 Boombox is also affected.

Thank you.
