microphone will not pick up my voice, in xbox live party, it shows my mic is plugged in, also when connecting wire to controller it makes the noise when connected and the microphone symbol in party indicates that it made a noise, but will not pick my voice up, it is not the cable, ive tried with my friends identical cable, it has to be the microphone. also ive have checked all settings, and made sure it was not muted and all was correct.
