Abstract
A highly versatile interface that is capable of digital and audio signal coupling is provided. The interface comprises contacts () that are used to couple both audio and digital signals, and separate contacts () that are used initiate and negotiate signaling mode transitions. Transitions can be effected without creating glitches, e.g., audible noise, in audio signals that are being coupled through the interface.
