w16355                      04/05/2004      LIBdd89151   Interface function for MP3 alert and playback.
                                                         - Added a function to let the SBCM task know
                                                           what accessory we're using with it's volume.

Ravi Subramanyan            08/05/2003      LIBdd27184   Need to remove the AM_L1_TCH_xxx macros 
                                                         completely from MME code 
                                                         - Resource manager would take care of this.

                                                         storing a user defined sound

Kevin Tang                  03/12/2003      LIBbb22639   Provided global variables to sync up the
                                                         midi sound complete and vocode invocation

Randy Scott                 09/10/2002      LIBbb53982   Adding new macro to check when MIDI starts

Pazit Gold                  05/01/2002      LIBbb28837   During a call the voice isn't heard.
                                                         Catchup from CRs: LIBbb25819 and LIBbb28225.
