My TV (UN55KS800DF) was connected without issue to my Yamaha (YAS-107) soundbar via HDMI-ARC for several years. The other day, it stopped working. I tried the usual fixes, new cable, reset the TV, reset the soundbar, check all the setting, got software updates. No luck. I was concerned it was the soundbar, so I borrowed a friends soundbar which was working fine with his TV. The same thing, no sound. Otherwise, the TV seems fine. One more clue - I believe this occurred when I tried to use the flakey bluetooth audio output on the TV. I've used Bluetooth before, but this feature has always been flakey and rarely works. I did reset everything afterwards. But after that, the ARC does not work. Any ideas?
