104 * @brief routing endpoint
106 * @details node is a routing endpoint in the GenIVI audio model.
107 * In pulseaudio terminology a routing endpoint is one of
109 * @li node is a pulseaudio sink or source. Such node is a
110 * combination of pulseudio card/profile + sink/port
111 * @li node is a pulseaudio stream. Such node in pulseaudio
112 * is either a sink_input or a source_output
