Wii's Guitar Hero III not down with surround sound?

[wraggster]

We don't know who thought it'd be smart to mess with the gods of rock, but choosing not to include surround sound support for Guitar Hero III just doesn't sound like an intelligent move. Nevertheless, a assemblage of Wii gamers are reporting that the game is outputting audio in mono, despite the packaging advertising that Dolby Pro Logic II is supported. We've even seen users with Pro Logic II-capable decoders explain that while other Wii titles sound fine, GHIII in particular refuses to cooperate. Supposedly, Activision is busy looking into the problem, but there doesn't seem to be a definitive time frame for when we can expect a fix. So, any of you shredders out there experiencing something similar, or have we only heard one channel, er, side of the story?
