how to play sound instaed Headset ,from speaker directly on android?

I am trying to play a media file and Listening it on Headset, Now I am trying to give a soft button that using fo开发者_如何学运维r SpeakerOn and Speakeroff.

mAudioManager.setMode(AudioManager.MODE_IN_CALL); 
mAudioManager.setSpeakerphoneOn(true);

I have give permission also in Androidmanifest.xml . But on calling these Apis, Mode is changed and using isSpeakerOn() api it showing the speaker status as we expected but In real time I am still getting sound from Headset only not from Speaker?

Give me some guideline so that we can achieve this switching of sound from headSet to Speaker?
