I have recently prewired a family room as i did 3 years ago. In wall 1 HDMI, and 5 channels of coax. Now I’m adding a smart tv with a sound bar but to my horror the later technology has the sound bar powered and wired via a optical cable or hdmi. My issue is I can link the sound bar via optical or hdmi “arc” to the tv. The issue is I only have 1 hdmi cable to my media cabinet 15 feet away and it’s buried in the wall. I have 3 additional devices, Satalite, Blu-ray, and PlayStation. Additionally I have a receiver in place attached to my outside speakers. My wife will kill me if my only option is to open any walls. Help?
