UO Second Age

Hello!
As the title says I have a Supremely Annoying Beeping Bug of Vanq.
I don't know what occurs it,but after shutting down UO,it's still beeping.
It's louder than foobar2K
Sometimes it disappears if I play Cs for example,but sometimes it keeps beeping while playing.
Helpz pls?

If I were you, I'd just re-install my operating system.

Shot in the dark here. Sounds like your sound card is getting stuck on an audio stream when UO tries to release it. Try updating your sound drivers.
