I have tried: 2 monitors are connected to a DP MST hub, and the DP MST hub is connected the computer. Each PCM can be muted independently. I haven't tried: the first monitor is connected the computer and another monitor is connected to the first monitor. Suppose it should be the same (I'm not very sure). As you know, we use converter to control the mute. Each PCM/device entry uses a different converter.
