Soundpool不播放任何声音

Question

edittexts在点击时不播放任何声音。我最后一次创建这种设置是有效的。现在它没有。有什么问题？

声音等级：

public class MySound {

    private AudioAttributes audioAttributes;
    private SoundPool soundPool;
    protected int soundClick;

    public MySound(final Context context) {
        audioAttributes = new AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                .setUsage(AudioAttributes.USAGE_MEDIA)
                .build();
        soundPool = new SoundPool.Builder()
                .setMaxStreams(10)
                .setAudioAttributes(audioAttributes)
                .build();
        soundClick = soundPool.load(context, R.raw.click, 1); 
    }

    public void setEtSound(EditText editText) {
        editText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                soundPool.play(soundClick, 0.5f, 0.5f, 0, 0, 1);
            }
        });
    }

}

片段：

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_1, container, false);

    mySound= new MySound(getActivity());
    mySound.setEtSound(etLoginUsername);
    mySound.setEtSound(etLoginPassword);

    return view;

}
