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
也许这有帮助:
播放声音时发生的一件事是电源管理阻止计算机进入睡眠状态.使用 pmset -g
您可以看到所有正在发生的电源管理内容.
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.
因此,当coreaudiod"阻止睡眠时,机器显然正在播放一些声音.
So, when sleep is prevented by "coreaudiod" the machine is playing obviously some sound.
这里是 pmset -g
在 iTunes 播放时吐出的内容:
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)
