+ *  \param c_aud_out Audio OUT endpoint channel connected to the XUD
+ *  \param c_aud_in  Audio IN endpoint channel connected to the XUD
+ *  \param c_aud_fb  Audio feedback endpoint channel connected to the XUD
+ *  \param c_midi_from_host  MIDI OUT endpoint channel connected to the XUD
+ *  \param c_midi_to_host  MIDI IN endpoint channel connected to the XUD
+ *  \param c_int  Audio clocking interrupt endpoint channel connected to the XUD
+ *  \param c_clk_int Optional chanend connected to the clockGen() thread if present
+ *  \param c_sof  Start of frame channel connected to the XUD
+ *  \param c_aud_ctl Audio control channel connected to  Endpoint0()
+ *  \param p_off_mclk A port that is clocked of the MCLK input (not the MCLK input itself)
