AppleScript的：检查电脑在播放任何声音 [英] Applescript: Check if computer is playing any sound

问题描述

试图找到我的脚本，以检查是否有任何声音/音频当前播放的计算机上的一种方式。如果是这样，有没有办法找出哪些应用正在播放的声音？

Trying to find a way for my script to check if there's any sound/audio being played currently on the computer. And if so, is there any way to find which app is playing sound?

推荐答案

也许这可以帮助：

在播放声音出现这种情况的一件事是，电源管理模块的电脑去睡觉。随着 pmset -g 你可以看到所有正在发生的电源管理的东西。

One thing that happens when a sound is played is that the power management blocks the computer to go to sleep. With pmset -g you can see all the Power Management stuff that is going on.

所以，睡觉的时候通过coreaudiodpvented机器打显然有些声音。$ P $

So, when sleep is prevented by "coreaudiod" the machine is playing obviously some sound.

下面是什么 pmset -g 吐出来时的iTunes播放：

Here what pmset -g spits out when iTunes is playing:

Currently in use:
 womp                 0
 halfdim              1
 sms                  1
 hibernatefile        /var/vm/sleepimage
 gpuswitch            2
 networkoversleep     0
 disksleep            10
 sleep                10 (sleep prevented by iTunes, coreaudiod)
 hibernatemode        3
 ttyskeepawake        1
 displaysleep         10
 acwake               0
 lidwake              1

结果
