+   PURPOSE : This module contains Audio Interface functions.
+
+   HISTORY  :
+
+    	Nov 07, 2006 ER: OMAPS00102732 x0pleela
+	Description: FFS Support for Intel Sibley Flash - Intel 256+64 non-ADMUX (PF38F4050M0Y0C0Q)
+	Solution: Closing the opened directory if readdir is not successful and the new code 
+   			is under the compilation flag FF_MMI_RELIANCE_FFS
+   			
+ 	Sep 11, 2006 DR: OMAPS00094182 xrashmic
+ 	Description: midi and mp3 files is not being populated on accessing corresponding menu, but only during bootup
+ 	Solution: Populate files on accessing the "browse files" list
+
+   Jun 06, 2006 REF: ERT OMAPS00070659  x0039928  
+   Bug:MP3 RWD and FWD function - MOT
+   Fix: Forward and Rewind functionalities are handled.
+
+
+   Jun 02,2006 REF: DR OMAPS00079746  x0039928  
+   Bug:MMI displays 'Playing' when trying to play a wrong file
+   Fix: MP3 playback error is handled.
+       
+   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.

+   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.
