+|                 Instruments Berlin, AG

++-----------------------------------------------------------------------------
+|  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).

+   	              
+ 	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

+            device/driver supports playing multiple sounds simultan-
+            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
+            not support playing multiple sounds simultaneously, the
