How would I do the reverse? That is, turn smart speakers into regular speakers. I have a Sonos Move but it can't play audio from my desktop PC with no bluetooth. I could buy a bluetooth dongle, but honestly I find wired connections easier to manage than pairing bluetooth devices, especially when you need to switch paired devices. I was hoping this OtterCast would have both bluetooth and line-in so I could do this (connect the bluetooth to the Sonos and the line-in to a desktop or other device).
