If it weren't bad enough that Activision shipped out Guitar Hero III with no offline co-op quickplay mode, a few careful listeners have noticed another thing they left out - a few channels of sound.
Audiophilic owners of Guitar Hero III for the Wii have noticed that not only does the game not support Dolby Pro Logic II surround sound systems (despite that feature being advertised), but it doesn't even output sound in stereo. As we all know, it's nearly impossible to pass "Cult of Personality" on Expert unless the manic shredding of Living Colour guitarist Vernon Reid washes over you from six different angles.
Apparently, Activision is looking into the problem, though they said in regards to a fix, "the time frame is still unknown." For the time being, we're afraid you're going to have to learn to rock out monaurally.
