That is not really the picture I was after. Can you open Roon on your PC and go to the settings menu and select “Audio”.

The zone you have called SLS ..... is that your ID41 ? Do you have a Sooloos core still running somewhere?

Having had a look at the user manual for the Cisco devices you have I am amazed anyone would be able to make these work in a domestic setting. A factory reset will mean nothing if you don’t know what is on or off by default. I wouldn’t want to navigate a managed switch. Looks terrifying.

Report back when you have other switches to try.

Good luck
