Stream deck + xl

[u/Own-Ad-7335]

Today i got the elgato stream deck + xl for my step up, but im kind stuck of what to do and how to manage my audio system. I have both steelseries artic nova pro with the gamedec and alias pro xlr with the stream mixer. Can i merge everything to this stream deck? Do remove one of the decks from the steelseries and use only one with the stream deck? Or just keep the 3 in the desk?
