**                  used by the phone to initialize audio paths or for other
**                  initialization purposes.

**
** Description      This function is called by the AG before the audio connection
**                  is brought up, after it comes up, and after it goes down.
**
** Parameters       handle - handle of the AG instance
**                  state - Audio state
**                  codec - if WBS support is compiled in, codec to going to be used is provided
**                      and when in SCO_STATE_SETUP, BTM_I2SPCMConfig() must be called with
**                      the correct platform parameters.
**                      in the other states codec type should not be ignored
**
** Returns          void
