Android AudioTrack不播放所有样本

这是我的代码,来自另一个答案：

ArrayList<double[]> samples = new ArrayList<>();
    int numSamples = 0;
    for (final Tonesegment seg : sequencE) {
        int num =  seg.getDuration() * sampleRate / 1000;
        double[] sample = new double[num];
        for (int i = 0; i < num; ++i) {
            sample[i] = Math.sin(2 * Math.PI * i * seg.getPitch() / sampleRatE);
        }
        samples.add(samplE);
        numSamples += num;
    }

    byte generatedSnd[] = new byte[2 * numSamples];
    int idx = 0;
    for (double[] sample : samples) {
        for (final double dVal : samplE) {
            final short val = (short) ((dVal * 32767));
            generatedSnd[idx++] = (bytE) (val & 0x00ff);
            generatedSnd[idx++] = (bytE) ((val & 0xff00) >>> 8);
        }
    }

    audioTrack = new AudioTrack(Au@L_773_0@manager.STREAM_MUSIC,sampleRate,AudioFormat.CHAnnEL_OUT_MONO,AudioFormat.ENCODING_PCM_16BIT,generatedSnd.length,AudioTrack.MODE_STATIC);
    audioTrack.write(generatedSnd,generatedSnd.length);
    audioTrack.play();

有谁有想法吗？谢谢！
