According to some aspects an electronic device adapted to detect whether it is coupled to an audio system. The electronic device includes a pulse generator adapted to generate a pulse on a ground return line of the electronic device, and a detector adapted to observe if a response signal is received by the electronic device corresponding to the pulse. If the response signal is received, the electronic device determined that it is coupled to the audio system
