Hi. I took a look at the troubleshooting FAQ and I have already verified that CEC on my LG TV is turned on. Also, as for ARC, I have verified that sound output is set to ARC/HDMI and the digital sound setting is set to Auto.
I have tried turning CEC off, then on again. This did not fix the problem. I unplugged the soundbar for a while and plugged it back in. This did not fix the problem.
The TV model is a LG 43UM7300AUE and the soundbar is a Yamaha ATS-209. The Roku Device ID is S0J732AYVCCF. The TV, soundbar, and Roku are running their most recent firmwares.
I am wondering.... If I perform a factory reset on the Roku and do NOT set up the ability to control the TV with the Roku remote, if I would still have this problem. This would not be ideal, as I want this feature. But it is just a thought.
Just a note: After the TV is on, even though the soundbar does not "wake up" when the TV is powered on, if I manually turn the soundbar on with the soundbar remote, the soundbar works fine over HDMI. Until I turn it off. Then when I turn the TV on again the soundbar stays off and there is no sound.
This, as I've mentioned, only happens when the Roku is plugged into the TV. If I unplug the Roku, the soundbar wakes up with the TV and turns off with the TV, as it should. Thanks,
MattL2 I don't have a solution but just a suggestion to try to isolate the problem. What happens if you plug an HDMI cable not connected to anything into the TV? Does the soundbar work correctly then? If not this means the problem is with the TV and not the Roku. If the soundbar works correctly with a blank HDMI cable it likely means the Roku is causing the problem.
Up until I bought the Roku, I had a video game console plugged into the same HDMI port on the TV and I never had this problem. It was after I bought the Roku and unplugged the game console to make an HDMI port available that the problem started. So I think it's safe to say the roku is somehow causing the problem.
Was there ever any resolution to this? I just got an Ultra and I'm having the same problem. It worked perfectly with my fire stick. I wanted to switch over to Roku so I went with the top-of-the-line model and it's not working. My TV speakers are weak and sound bad so I got a Yamaha bar a few years ago. The bar worked perfectly with DirecTV and Fire Stick but Roku jacks up the ARC for some reason.
