Win32播放声音 [英] Win32 Play sound

问题描述




bool Win64Sound :: PlayIt（）{

    // return !! PlaySoundW（WideStringSoundFileName.c_str（），NULL，SND_FILENAME）;

    return !! sndPlaySound（StringSoundFileName）.c_str（），SND_ASYNC）;

}

bool Win64Sound::PlayIt() {
    //return !!PlaySoundW(WideStringSoundFileName.c_str(), NULL, SND_FILENAME );
    return !!sndPlaySound(StringSoundFileName).c_str(),SND_ASYNC);
}

我使用 PlaySoundW测试了这个成员函数（ ）并没有问题，但
sndPlaySound（）不会产生任何声音。我正在链接
-lwinmm -mwindows

I have tested this member function using PlaySoundW() and had no problems, but sndPlaySound() does not produce any sound. I am linking against -lwinmm -mwindows

我使用的是Win 8.1机器。

I am using a Win 8.1 machine.

这里的任何人都知道可能出现什么问题？

Anyone here knows what could be the problem?

推荐答案

嗯，除了sndPlaySound行中明显的编译器错误，你有sndPlaySound的SND_ASYNC但不是PlaySound，是否将SND_ASYNC添加到PlaySound，或者从sndPlaySound中删除它会有什么区别？

Well, besides the obvious compiler error in the sndPlaySound line, you have SND_ASYNC for sndPlaySound but not for PlaySound, does adding SND_ASYNC to PlaySound, or removing it from sndPlaySound make any difference?

否则，唯一要注意的是确保StringSoundFileName具有正确的路径，因为它是PlaySound使用的WideStringSoundFileName的不同变量。

Otherwise, the only other things to look at is to make sure that the StringSoundFileName has the correct path, since it is a different variable to WideStringSoundFileName that PlaySound uses.

无论如何，仅为了向后兼容性而维护sndPlaySound。如果可以的话，我建议你把所有内容改为PlaySound。更重要的是，这两个基本上已被WASAPI取代。

Anyway, sndPlaySound is only being maintained for backwards compatibility. If you can, I would suggest you change everything over to PlaySound anyway. What's more, both of these have basically been superseded by WASAPI.
