https://t.co/w6M1lCGmRsInfus: I'm not 100% sure how the sound settings in WoW work. We are just playing a sound on a channel, and assume that it uses the sound volume of that channel. So that might be a wow bug, or a misunderstanding how it actually works. Create a ticket and we'll figure that out with you.
