Android – MediaPlayer Buffer Size in ICS 4.0

Would it be possible to see the code where you’re start()ing the MediaPlayer?

Are you using the STREAM_MUSIC audio stream type?

player.setAudioStreamType(AudioManager.STREAM_MUSIC);

Have you also experimented between player.prepareAsync(); and player.prepare();?

There was a similar issue last year I remember, where the solution was to: start, pause and then onPrepared to start():

player.setAudioStreamType(AudioManager.STREAM_MUSIC); 
player.setDataSource(src); 
player.prepare(); 
player.start(); 
player.pause(); 
player.setOnPreparedListener(new OnPreparedListener() {     
@Override
                public void onPrepared(MediaPlayer mp) {
                    player.start();                
                }
          });

Unlikely to be the fix in this case, but while you’re spinning your wheels this might be worth a shot.
