Right after 2.4 Patch was released, the o-boards' Tech Support forum popped up with several "2.4 Audio Issues" threads, in fact I posted one myself.
To the few that Blizz actually responded to, they said in essence "Update your Drivers, we didn't really change anything, we just added a sound quality slider."
Well, nearly a week later, I go to the o-boards, curious if they acknowledged the problem yet or not, and what do I see?
A Blizz poster saying "We think we found the bug, it seems sounds are being piped to non-existent channels and this is causing errors."
Everyone wanna say it together?
