New Guild Halls Killing Sound

Hi, I have a strange problem.

My sound works perfect at all times, except when I enter one of the new guild halls. If i travel to an alliances new guild hall (as my guild has an old one) the sound dies on guild wars, Team speak, everything. Then i restart guild wars and its fine, enter a new guild hall again and it dies.

If i've started in my own guilds old guild hall then happen to have a battle against a team with a new one this also kills the sound.

Anyone else had this problem?

I have an audigy 2 ZS sound card

hmm i just turned down the sound quality and it works.... odd
