I have recently installed Sonos Arc in a Garden Room TV, I have ceiling speakers also, wired from a Sonos Amp. The plan was to connect HDMI to the TV and also the ARC direct to the TV with HDMI. My issue is that the TV I bought only has 2 HDMI ports, horrendous I know. Can I use Digital Optical out for Arc and use the Arc HDMI for the Amp and then have both speakers working together?  Then it will free up another HDMI for my Amazon fire stick. Or is there a better solution? Thanks
