Players over at the official World of Warcraft forums want Blizzard to admit that its developers committed an error in implementing the MMO game's voice chat feature. According to some players, it looks like Blizzard put in a software driver that adversely affects hardware acceleration.

Forum moderator Drysc answered that the new sound engine and the chat feature are not actually related. While the voice chat feature does rely on the software upgrade, the said sound engine has been planned long before. He added that the new engine has a lot more features than the old system. But then Drysc admitted:

We do understand that the switch to the new sound engine has caused some issues. Any undertaking and replacement of such a large system within the game, and especially with so many and varied machines running it, there are sure to be some growing pains.
