@dumganhar
我们这边收到一个类似崩溃日志

在这个手机上必现，但不知道什么原因。受影响的用户也不小，求教一个暂时的解决办法。

#5

IOS也声音时不时宕机

#6

void PcmAudioService::resume()
{
SLresult r = (*_playItf)->SetPlayState(_playItf, SL_PLAYSTATE_PLAYING);
SL_RETURN_IF_FAILED(r, “PcmAudioService::resume failed”);
}

想不出这行里面怎么可能会出错。。。

#7

我们的游戏有类似问题，这里有堆栈，在google play上出现的几率还是蛮大的

会不会是 playItf 为空，或者野指针了？

#9

我看了一下，确实不知道什么原因，费解。。。不过这种日志不是个例，我明天等拿到这个出问题的机器在看看具体原因

#10

@minggo @dumganhar 我们使用的是 cocos2d-x 3.16版本的音频 依然有这个问题

有没有出现此堆栈时的 logcat 日志？

#12

有开发者提 PR，修复这个问题，可以尝试
