Currently, I am using the "Set silent" action but it causes some bugs (music doesn't trigger if it's Set to not silent on Web browser and Set silent doesn't work on Android).
I tried setting Master volume to -800db, for example. And that works fine on the browser (although it's an ugly workaround...)
Maybe some of you guys know how to do this. It bothers me that when I set "not muted", the music doesn't trigger back. I've been trying stuff, but it doesn't seem to work.
Let me know if you have a solution for this.
