为什么我的 SoundPool 静音？
我设置了 SoundPool，并在 onCreate() 中加载声音资源：
soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
soundId = soundPool.load(this, R.raw.edible_underwear, 1);
然后我尝试在 onClick() 中播放此声音两次code>，一慢主要在左扬声器，一快主要在右扬声器：
soundPool.play(soundId, 0.9f, 0.1f, 0, -1, 0.7f);
soundPool.play(soundId, 0.1f, 0.1f, 0, -1, 1.5f);
听不到声音。我摆弄了数量、优先级和费率。至今无济于事。我错过了一些明显的东西吗？
I setup my SoundPool, and load a sound resource as this in onCreate():
soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
soundId = soundPool.load(this, R.raw.edible_underwear, 1);
And then I try to play this sound twice in a onClick(), one slow mostly in left speaker, and one fast mostly in the right speaker:
soundPool.play(soundId, 0.9f, 0.1f, 0, -1, 0.7f);
soundPool.play(soundId, 0.1f, 0.1f, 0, -1, 1.5f);
No sound can be heard. I have fiddled with the volumes, priorities and rates. So far to no avail. Am I missing something obvious?

事实证明，
SoundPool有两个错误/限制。soundId。因此，您必须查看日志，并向 Android 之神祈祷您的示例适合目标设备。Turns out that
SoundPoolhave two bugs/restrictions.SoundPoolthat do not fit in ram will not result in an exception being thrown, nor is there asoundIdreturned that can be checked for failure. So you must look at your logs, and pray to the Android gods that your samples fit on the target device.
