I currently have a Sonos Port connected to a 2009 pioneer receiver, that I also use for movie surround sound. I would like to buy a soundbar and I was looking at the Samsung HW-Q950A. Alas, it only has HDMI and optical inputs The port just has RCA and digital Coax. Is there any way possible to connect these? I am passing on the Sonos Arc because I can get same thing with Samsung for $1300 that will cost me $2k for the Sonos.
