<p>A system comprises a pulse generator (615) configured to provide a control pulse a transmission gate (603) configured to interrupt a path between a communication device (307) and an auxiliary device (303) during the control pulse; and a pulse transmitter (607) responsive to the control pulse and configured to inject an interrupt pulse in the path while the path is interrupted. A corresponding method of providing an interrupt signal in an audio path between a source and a sink includes interrupting an audio path between the source and the sink, injecting an interrupt pulse in the audio path while the audio path is interrupted, and then reconnecting the audio path.</p> |
