Narrative:

While in cruise flight my copilot checked in with center. We were deviating around WX and discussing our plan of attack (we were going to an alternate due to the thunderstorms at our destination). After awhile (about 5 mins) we saw an MD80 about 1000 ft below us. We commented on the fact that the controller did not call the traffic out to us. At that point we realized that the radio was silent. We then attempted to call center who then told us our microphone was stuck and we should have it fixed, he also called the traffic out to us. In retrospect the only way to solve this problem should it crop up in the future is to cut down on interplt communication and listen up more to the radio.
