Audio announcements are performed through the aricraft built-in sound system (microphone, speakers, etc.). The IFE system is responsible for dispatching these announcements to each Seat TV. This function receives the audio streams from the aircraft and forwards it to the IFE applicative server. The implementation of this function is likely to be specific to each aircraft.
