   MODULE  : MFW_AUD

   PURPOSE : This module contains Audio Riveria Interface functions.

   HISTORY:

	Mar 28, 2007  DR: OMAPS00122762 x0039928
	Description: MM: Deleting a PCM Voice Memo message in one particular memory, 
	delete them in all memories
	Solution: voice memo position and pcm voice memo position is provided for all the devices.
	
    July 03,2006 REF :OMAPS00083150  x0047075
    Description :Audio muted on call swap / hold
    Solution :Function call hl_drv_enable_vocoder() and hl_drv_disable_vocoder() are replaced with hl_drv_set_vocoder_state()  
	Mar 15, 2006   ER: OMAPS00067709  x0pleela
	Description: Voice Buffering implementation on C+ for PTT via PCM API 
	Solution: Defined new macros of folder and file names for PCM voice memo and Voice buffering
			Defined new macros for Microphone and network gain of PCM VM and Voice buffering
			Defined new functions set_voice_memo_type, get_voice_memo_type, set_voice_buffering_rec_stop_reason
		Function: mfw_aud_vm_delete_file
		Changes:Handling file deletion forPCM voice memo also

		Function: mfw_aud_vm_start_playback, mfw_aud_vm_stop_playback, mfw_aud_vm_start_record,
				mfw_aud_vm_stop_record, mfw_aud_vm_get_duration, mfw_aud_vm_set_duration
		Changes: Added code to call respective audio APIs for PCM voice memo and voice buffering

	Feb 24, 2006    ER: OMAPS00067709 x0pleela
	Description: Voice Buffering implementation on C+ for PTT via PCM API 
	Solution: Defined a global variable gPcm_voice_Memo which indicates which Voice memo is active 
			and corresponding audio APIs will be invoked and duplication of code is avoided
	
	Feb 24, 2006    ER: OMAPS00067709 x0pleela
	Description: Voice Buffering implementation on C+ for PTT via PCM API 
	Solution: Adding new macros PCM_VM_FILE_NAME, PCM_VM_FOLDER to define new files for PCM voice memo
			Following functions are implemented to support PCM voice memo feature
				mfw_aud_vm_pcm_delete_file: Delete the file which held the PCM Voice Memo
				mfw_aud_vm_pcm_start_playback: Start playback of a previously recorded PCM Voice Memo
				mfw_aud_vm_pcm_stop_playback: Stop playback of a previously recorded PCM Voice Memo
				mfw_aud_vm_pcm_start_record: Configure Riviera and start recording a PCM Voice Memo
				mfw_aud_vm_pcm_stop_record: Stop recording a PCM Voice Memo
				mfw_aud_vm_pcm_get_duration: Get the duration of the previously recorded PCM Voice Memo
				mfw_aud_vm_pcm_set_duration: Set the duration of the previously recorded PCM Voice Memo
	
    Apr 06, 2006    ERT: OMAPS00070660 x0039928(sumanth)
    Description: Need to reduce flash foot-print for Locosto Lite 
    Solution: Voice Memo feature is put under the flag #ifndef FF_NO_VOICE_MEMO to compile 
    out voice memo feature if the above flag is enabled.

    Mar 03, 2005 REF: CRR MMI-ENH-28950 xnkulkar
    Description:  RE: Vocoder interface change
    Solution: Function call 'enable_tch_vocoder()' is replaced with new functions 'hl_drv_enable_vocoder()'
    		    and 'hl_drv_disable_vocoder()'

    Aug 25, 2004  REF: CRR 20655  xnkulkar
    Description: Voice Memo functionality not working
    Solution:	  The voice recording functionality was failing because 
    			 " mmi" folder is not present. As a solution, we create the 
    			 "mmi" folder and then proceed with recording.
