I have one of those microphones thats attached to a headphone. Today, i wanted to sing for my friends on msn and plugged the headphones into the black jack and the Microphone into the red one, but to my frustration, my friends couldnt hear anything... I thought i had plugged it into the wrong jack, but switching it over doesnt work and i am pretty sure i had plugged it into the right jack... coz the headphone seems to work i can hear things fine... I cant find the microphone show up under sound options so i was wondering why it wasnt recognised, and if doesnt need to be reconginsed and installed, so how do I get it to work??? coz when I tap it it doenst make the sound that all microphones make when you tap them and i cant speak through it help!!!!
