Narrative:
While entering a traffic pattern for downwind, my student reported entering 45 degrees for downwind. At that point the microphone became stuck. Upon announcing downwind, I noticed an airplane crossing left to right for a base leg, and that my student was lined up for on a 45 degree entry to the wrong downwind, but only because the last transmission heard by the C172 was for the runway which we were lined up for. According to other instructors in the area, they were aware of my intentions as well as the fact that we were experiencing radio problems. What the other CFI's were not sure about was the BE36's intentions. One CFI stated that he never heard a proper radio call from the BE36, but had heard all of the C172's calls. Evasive action was taken by the C172 to avoid the BE36.
