Issue with AVPlayer any PJSIP

[terente.alex@xxxxxxxxx (Alex Terente)]

You have to set audio route back to speaker again before playing a new sound in
AVAudioPlayer. 
Code: 

//set sound to speaker
UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,
sizeof(audioRouteOverride), &audioRouteOverride);
