+-----------------------------------------------------------------------------
|  Purpose :  This Module defines the audio driver interface.
|             for the G23 protocol stack.
|
|             This driver is used to control all audio and audio-related
|             devices of the mobile such as speaker, microphone, etc.
|             A device, e.g. a speaker, may have the capability to play
|             sounds and/or melodies indirectly. This means a sound
|             generator may be attached to a speaker or its amplifier.
|             The format of the sound/melody images is implementation
|             dependent and therefore not in the scope of the generic
|             driver interface. Therefore a application may play pre-
|             defined, driver specific sounds identifying them via a
|             sound ID. In addition the API of this driver has foreseen
|             that an application may copy a sound image into its local
|             buffer, modify it and let it play by the driver. In this
|             case the application has to have the knowledge about the
|             sound image format.

|  History :  
|		  Apr 04, 2005    REF: ENH 30063 xdeepadh
|		  Description: Buzzer removal activity for Locosto MMI
|		  Fix:All the Buzzer related calls are under the  compilation flag FF_BUZZER.
|			The GSM tones which were playing in the buzzer are now routed to the speaker(Audio).

	$History: 

   	              
 	xpradipg - GSM-ENH-32494 : 23 June 2005
 	Description:	Support for various audio profiles
 	Solution:	The support for audio device's carkit/headset/loudspeaker/handheld.
 			The audio device is enabled as per the user actions.	

	June 13, 2005	REF : GSM_ENH_32062 - xpradipg
	Description:The audio uplink not working in the connected call
	Solution:	The audio uplink was configured to mute state at initialization
				The configuration is changed to be in unmute state

	Apr 26, 2005   REF : CRR 30627 xpradipg
	Bug :	Replace the ABB APIs with Audio Service APIs
	Fix :	The ABB APIs are used in muting/unmuting and setting the volume of
			the speaker and microphone. These ABB APIs are replaced with the 
			audio serivce APIs

  PURPOSE : This function is used to play a sound or melody. The

            eously, i.e. accepting multiple calls of audio_PlaySoundID().
            If the calling process should be notified when the sound has
            stopped playing automatically, the signal AUDIO_SIGTYPE_
            SOUNDEND must be set using the audio_SetSignal() function.
            If the special driver implementation or the device does
            not support volume control, the driver ignores the value.
            If the sound can be played, the function returns DRV_OK.
            If the device is currently playing the sound identified by
            the parameter in_SoundID, the function returns DRV_INPROCESS.
            If the device/driver is currently playing a sound, but does
