A Pro Gamer Wired Twin Microphone Pack was bought to be used with the We Sing Down Under Wii Game, and it's not working. The consol/game is not registering that the microphone is plugged in, however the microphone that came with the game works. All advice would be much appreciated.

Maybe the Nintendo Wii overheated because you played with it for too much. Give it a rest and go back to it later.

My Nintendo ds lite also would not respond to voices. I have brain age 2 and Zelda. In the Zelda options there is a mic test. This will show a graph bar that measures your voice. Well the mic was not working at all for either game. I simply took out the battery and held the power slide for a couple seconds. Amazingly the mic works now for both games. I do not know if moving the power slide is significant, but on computers to de-static them you remove all power sources(battery and ac adapter) and hold the power button for 10 seconds.

I had the same problem but i found out if you only have 2 remotes and you use them for the guitar and the drums the mic wont work.
you have to use one of the remotes for the microphone
first unplug your wii console then hook up the mic to the consol
turn the wii on and use the remote for player one to activate the game without the other instruments connected.
after you get the game started it will recognize the microphone. then connect the other remote to which ever instrument you want to use. you have to have three remotes to use the guitar the drums and the microphone
