1. A host communication circuit that is adapted to be connected to a client communication circuit by means of a clock wire, a selection wire, a first data wire and a second data wire, the host communication circuit being configured
to transmit a digital selection signal over the selection wire to the client communication circuit, the selection signal determining either an audio transmission mode or a client communication mode; and
to transmit digital audio data of a first channel and a second channel over the first and the second data wire to the client communication circuit in the audio transmission mode, and to perform bidirectional client communication over the first and the second data wire in the client communication mode.
