Steps to Reproduce:

    schedule([](float dt){
        for (int i = 0; i < 20; ++i) {
            AudioEngine::play2d("fonts/audio_music_004.mp3");
            std::this_thread::sleep_for(std::chrono::milliseconds(5));
            AudioEngine::stopAll();
        }
    }, "bbbb");

Result:

Will this bug fixed at 3.17 version?

formatCvt commented 6 years ago

confirm bug on cocos2d-x version 3.16 too

wbbtcool commented 5 years ago

This bug will still on 3.17.1. I use schedule function delay play sound. Temporarily circumvented this problem. 

    node->scheduleOnce([=](float time){
        AudioEngine::play2d(filePath);
    }, 0.01, "play_sound");

I still face problems after putting delay. Anyone has the solution?

jhyoo2 commented 2 years ago

I also found the same problem.. How can I not solve this? It's a problem because the game freezes. It's a really big problem.

播放的时候会返回一个Id,记录下这个id开始播放的时间,销毁的时候判断一下这个时间是否超过比如0.5秒,如果超过则销毁，否则延迟到0.5秒后再销毁就可以了

QuiQiJingFeng commented 3 months ago

自己解码播放就可以避免这个问题了
