I recently bought a budget Panasonic 4K backup TV for my bedroom. I was a bit disappointed with the HDMI ARC performance with my Philips HTL2163B soundbar. It would work perfectly at times and other times no amount of tweaking would make it work. I resorted to using the 3.5mm audio jack in the interim and wasn’t happy with the sound output. Unfortunately my TV also only had an analog SPDIF output. So I had to buy both an SPDIF cable and Optical Converter to make it work. The results are pretty impressive and almost on par with HDMI ARC in my opinion. So a must buy for all those people who face similar issues.
