&引用；ALSA lib pcm.c:7843:（snd_pcm_recover）发生欠载尝试播放音频时julia出错

有人能说出在JULIA中播放音频时的错误吗？如何解决这个问题？我正在使用图书馆的音频。试着播放正弦曲线

julia> x=sin(0:.01:2*pi*500*5);

julia> using AudioIO

julia> play(x)

如果您在这里没有得到答案，请向提交问题。

很抱歉，在github上看到您的问题，但不知道有这么一个问题

ALSA上的Portaudio显然对错过回调截止日期非常敏感，并且倾向于挂断并将CPU固定在100%。最新版本的AudioIO（0.1.x）现在使用读/写API来portaudio，看起来更加稳定。它也不再像以前的版本那样需要C垫片来处理回调，因此它应该更容易安装

请尝试一下，让我知道它是否在您的系统上运行得更好（尽管github问题肯定是引起我注意的更可靠的方法）。

好的，我会这样做。几周后我将再次启动julia。所以，如果问题仍然存在，我们会让您知道。
