Question

我的SoundManager类使用SoundPool作为它的音频。我有一个声音会循环，1秒钟和2秒钟关闭，直到被告知停止。问题是这将执行一次，然后我注意到logcat中的错误说“SoundPool：创建AudioTrack时出错”，然后“AudioTrack：AudioFlinger无法创建跟踪，状态：-12”我的代码如下。知道为什么我会收到这个错误吗？

public class SoundManager {

    public SoundManager(Context c) {
        mContext = c;
        sp = new SoundPool(1,AudioManager.STREAM_MUSIC,0);
        spSound = sp.load(mContext, R.raw.tone4402, 1);
    }
    public void Tone3(int timer) {
        (new Thread(t3)).start();
    }
    final Runnable t3 = new Runnable() {
        public void run() {
            if(isPlaying == false) {
                isPlaying = true;
                Tone3Run();
            }
        }
    };
    public static void Tone3Run() {
        //1 sec on, 2 sec off, repeat for 2 minute
        Log.d("Sound", "Tone3 Playing");
        long startTime = System.currentTimeMillis();
        long currentTime;
        do
        {
            currentTime = System.currentTimeMillis();
            Log.e("Sound Manager", "Time:" + (currentTime - startTime));
            temp = sp.play(spSound, currentVolume, currentVolume, 1, -1, (float)1.0);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
            e.printStackTrace();
            }

            sp.pause(temp);
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        } while( ((currentTime - startTime) < 120000) && (boolStop = false) );
        sp.release();
        sp = new SoundPool(1, 4, 0);
        spSound = sp.load(mContext, R.raw.tone4402, 1);
        isPlaying = false;
}
