Question

I am developing a game and playing audio sounds using SoundPool and MediaPlayer. Every time when any audio sound plays, it shows error in LogCat.

public class MusicSoundResources {

    private static final String CLASS_TAG = "SoundResources";

    private static MusicSoundResources _instance;
    public static HashMap<String, MediaPlayer> mSoundPoolMap;
    private static AudioManager  mAudioManager;
    private static Context mContext;

    public MusicSoundResources() {

    }

    public static void initSounds(Context theContext) {
         mContext = theContext;
         mSoundPoolMap = new HashMap<String, MediaPlayer>();
         mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);

         loadSounds();
    }

    private static void loadSounds()    {
        mSoundPoolMap.put("swallowed", MediaPlayer.create(mContext, R.raw.swallowed));
    }

    public static void playSound(String soundTrackIndex, boolean loop) {
        MediaPlayer mediaPlayer = mSoundPoolMap.get(soundTrackIndex);
        float streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        streamVolume = streamVolume / mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);

        mediaPlayer.setVolume(streamVolume, streamVolume);
        mediaPlayer.setLooping(loop);
        mediaPlayer.start();
    }
}

These are two logs which display:

05-31 15:02:56.400: ERROR/AudioTrack(2384): getAudioMode[0]
05-31 15:02:56.400: ERROR/AudioR2VS(2384): The 11025 sample rate is not supported by R2VS solution.

Same problem occurs when I use SoundPool.

Tell me what is the supported sample rate.

Answer 1

Finally I got the answer for this. This error comes when we play sounds of bit rate higher than 11025 Hz. This is an an internal error of android media player.
