For my escape room I'm going to replace the inner works of a rotary phone by a Teensy 3.2 + Audio Shield. The players will have to find the right number to call. Up to that point, I will play WAV files (buzz tone etc.) from the SD card. After they called the right number, the Teensy will stop playing the WAV sounds.
Then the Game Master will speak to them through the Line In. As I gather it, the sound from Line In will directly go out to the jack plug, mixed with whatever the Teensy is playing. Is this correct?
Then my question: can I detect activity on the Line In? If yes, I can silence the buzz tone from the Teensy. (If no, I have to use another form of communication (a digital pin) to change its state from active to passive.)
