ROKU ULTRA GOES TO SNOW, SAMSUNG SOUND BAR, PANASONIC TV

We have the ROKU Ultra, purchased this year (2020). I have it hardwired to an ethernet port on my Verizon FIOS router. Initially the setup was Roku HDMI out to Samsung sound bar in, Samsung HDMI out to Panasonic Viera TV input. (this is a pretty old TV, over 10 yrs)


PROBLEM:
After performing fine for a few weeks, the picture would suddenly disappear and nothing but snow appeared on the screen. The audio could still be heard; it was only the picture that went to snow. Not black, as when the TV loses input signal, but white snow.

At first turning the Roku off and on would fix it - for a time. But picture loss started happening so frequently (every few minutes) that watching a program was becoming impossible. Then I tried turning the soundbar off and on, and that brought the picture back too. So to me this meant that maybe it wasn't the Roku Ultra. It had to be something about the signal passing thru the soundbar, and then... ???


SOLUTION:
I solved it by changing the configuration. Now I have the Roku feeding directly into the TV's HDMI in. I changed the audio feed to the Samsung soundbar to the TV's optical audio out. I made this change days ago and since then, no issues. Of course I had to change the soundbar's SOURCE to "D.IN", as opposed to HDMI, but the soundbar remembers the source setting. I only had to make the change once.

NOT PERFECT - 2 remotes
Using the optical audio feed from the TV into the soundbar means I have to use the Samsung soundbar's remote to change volume/MUTE in addition to the Roku remote for channels. The Roku remote does not control the volume. But I couldn't get that to work when it was hooked up the old way either, so I really don't care. And I did try many codes to make the Roku remote my "one and only" when it was hooked up the 1st way. But I'm glad I didn't spend too much time on it cause ultimately I had to change everything to the way it is now, and I did read somewhere on the internet (so it MUST be true!! ha) that if you use the TV's optical audio out w/a Samsung soundbar, you can't get the Roku remote to control sound.

Thank you for posting this. I was having the exact same issue and your solution seems to have worked for me as well.

I have the exact same issue with a Samsung UN65ES8000F Smart TV and two different models of Samsung sound bars. A model HW-T550 (2020), which I just purchased because I thought my older model sound bar (Samsung HW-450 2013) was too old to update its firmware in hopes it would resolve this issue -which it did not. I've updated the TV, the Roku, and the both sound bars to the latest available firmware codes for each component. I replaced the older HDMI cables I was using between the Roku and TV with new Monster brand HDMI cables rated for 4K, and I have moved the HDMI cable connection on the back of the TV from one HDMI port to another to eliminate the possibility of a bad HDMI port and nothing has resolved this issue. The only thing that worked was plugging the Roku directly into the TV which, of course, prevents the use of the sound bar which just sucks because the TVs built-in speakers are subpar at best. Very frustrating because I've posted this issue on another thread on this community board and I still haven't gotten a response from Roku.

Well that's totally unacceptable. I would be quite PO'd if I had to watch movies w/the TV's native speakers and nothing else. Your TV doesn't have any other alternate audio output to feed the soundar? That's beat. "You're beat.", as the saying goes.

I'm afraid you may have to invest in a new TV. Personally I find the sound about as important as the video. Not for everything, but for a movie? Definitely.

Re: ROKU ULTRA GOES TO SNOW, SAMSUNG SOUND BAR, PANASONIC TV

I was having the exact same problem with my Roku Ultra, Panasonic Plasma, Samsung soundbar combination. I found a solution that works for me and I can control everything with the Roku remote.

I ran one HDMI cable from Roku to the HDMI 1 port on the TV. Then I connect another HDMI cable to the TV  on port labeled HDMI 2 (ARC),  and the other end of that cable to the Samsung sound bar HDMI port labeled TV-ARC. Set the sound bar to D.IN, and it will automatically change to TV ARC. That’s it! 
This way you are using 1 HDMI cable to provide audio/video to the TV, and the second HDMI sends audio and volume commands to the soundbar. I think the problem we were having was because we were trying to do all of that with just one cable
