cocos2d-x 同时播放多个音效的问题

cocos2d-x 同时播放多个音效的时候，会发现有的音效放不出，有的循环音效放着放着就没了

后来发现猫腻在Cocos2dxSound.java里：

private static final int MAX_SIMULTANEOUS_STREAMS_DEFAULT = 5;

SoundPool构造的时候要指定并发音频流的数量

public SoundPool (int maxStreams, int streamType, int srcQuality)

Added in API level 1

This constructor was deprecated in API level 21.
use SoundPool.Builder instead to create and configure a SoundPool instance

Constructor. Constructs a SoundPool object with the following characteristics:

Parameters

maxStreams	the maximum number of simultaneous streams for this SoundPool object
streamType	the audio stream type as described in AudioManager For example, game applications will normally use STREAM_MUSIC.
srcQuality	the sample-rate converter quality. Currently has no effect. Use 0 for the default.

Returns

• a SoundPool object, or null if creation failed

这里cocos2d-x设置成5了（I9100设成3），可以手动改大一点，来解决问题

版本：cocos2d-x 3.0
