#5 Power on speaker/monitors/amps LAST

You'll never hear the pops that way.

This order of operations specifically avoids all such issues, on purpose.

Least you could do is maybe to totally power off your speakers when plugging unplugging live inputs/interface?

Also best practice is reversing steps to power down and disconnect, i.e. #5, #4, #3, #2, #1, then you're done.

Not saying this is an issue here, but I bet a large proportion of "IT'S NOT WORKING" posts on the forums and "something happened then I heard audio, don't know what or why" has to do with interfaces powering on and plugging in bad order or drivers otherwise getting crossed somewhere in the boot up. Evidence being, these users maybe only did a power cycle and something might have connected as it should.
