如何使用 python 代码在 ubuntu 中使右/左扬声器静音？

Question

I use os.system('amixer sset Master 0,-') to disable right speaker but when I change it to os.system('amixer sset Master -,0') it says that I'm using invalid option. Does anybody know what is the problem? and if this code doesn't work could you suggest any codes to disable left/right speaker??

Answer 1

os.system("amixer -D pulse sset Master 50%,0%")
最后，上面的代码对我有用:) 更改主百分比以减少/增加每一侧的音量。
