Im trying to get my Logitech Guitar Hero Microphone to work with MP3-G Karaoke homebrew. If I play a game like Guitar Hero, Abba Hits, X - factor etc.. through USB loader the Mic works great but when I go through the Homebrew channel to play Mp3-g the mic doesnt work at all. I have "sunfly" karaoke songs working but the mic isnt working at all.

Any help would be greatly appreciated.
