Many raiders are plauged by the verbal assault of dragons in sunspire atm (they keep the shout/breath sound on, over and over and apparently it even stacks)

I found out that by setting the "Effects" audio slider to 0 and back to a positive value gets rid of the bug (until it restarts). It would be nice to do this via a hotkey, because doing this midraid is not a real option, and playing without effect sound completely is also rather confusing (if you're used to it).
