   MODULE  : MFW_MP3

   PURPOSE : This module contains Audio Interface functions.

   HISTORY  :
   Nov 16,2005 REF: DR OMAPS00049192  x0039928
   Bug:MP3: The screen is not refreshed after the mp3 file completes playing
   Fix: The AUDIO_OK event recieved after mp3 file play completes is now handled 
   in mfw_mp3_test_start_cb()

   Nov 14, 2005    REF: OMAPS00044445 xdeepadh
   Description: Implementation of Test Menu for AAC
   Solution: The existing MP3 test Application has been enhanced to support the AAC file testing.
   The interfaces have been made generic to support both MP3 and AAC files.

   Nov 24,2005 REF: DR OMAPS00049192  x0039928
   Bug:MP3: The screen is not refreshed after the mp3 file completes playing
   Soln: A variable mfw_mp3_playstate is added to maintain the mfw play state.

   Description: Configuring the audio path for midi


   Jul 18, 2005    REF: SPR 31695   xdeepadh
   Bug:Problems with MP3 test application
   Fix:The window handling of MP3 Test Application has been done properly.
	
   Apr 06, 2005	REF: ENH 30011 xdeepadh
   Description: Replacing the Test Application compilation flags with new flags. 
   Solution:  Removed the Condition to call mp3 APIs, if L1_MP3 flag is enabled.
   This file will be compiled only if L1_Mp3 flag is enabled.
