Hi I am trying to downsize my monitoring setup to an Arc controller. This is working perfect with TotalMix managing it all. But I normally keep my Genelecs switched on and manage turning the power on the power conditioner.

When using the hardware monitor controller with the mute switch kept on, I get no loud pop or noises.

I had to turn everything back on, to check the Arc control setup is working as I need. However when I turned the power back on with no computer connected. There was indeed a loud pop and sounded bad. All the outputs were muted in a mute group this is what I had setup to mute all outputs. 

I have never had this pop issue before as the controller mute switch is always enabled.

Any ideas how to work around this ? Do I have to individually turn each speaker on / off  now ?
