I have posted a similar question previously but thought it deserves follow up. I recently obtained a Roku Ultra to use with my existing LG TV and Samsung Soundbar. Several people have offered "fixes" for my issue. Unfortunately none have solved my issue. I was just informed by Roku Customer Support that Roku does NOT have the capability to work with a NON-ROKU soundbar. I also just tried to reset up my Roku Ultra device. During the setup I read a statement that basically said ROKU cannot work with with other soundbars. I replaced a Firestick remote which easily connected to my LG TV and Samsung Soundbar. I'm shocked Roku does not have this ability. How disappointing!!
It's not that the Soundbar is a non-Roku Soundbar why it doesn't work, the reason is your Soundbar is connected by optical cable, that's why it won't work. If it was connected via hdmi cable, a Roku remote would control the Tv volume by IR, and in turn the tv controls the Soundbar via CEC signal over the hdmi cable. Yes Firestick remotes can be programmed for audio devices directly, Roku remotes cannot.

Thank you for the response. Can you please be more specific on the connections required? I am not very technical savvy so need all the support I can get. My LG TV has several HDMI IN connections HDMI 1 is also ARC. My TV settings are as follows: TV Speaker-Off, ARC mode -On. AV Sync - On. My Samsung soundbar has an HDMI IN and HDMI OUT. The Roku streaming device only has an HDMI OUT. Can you provide the connections please. I believe you also mentioned CEC. I'm not sure what that is. Thank you in advance.
MY SOUNDBAR IS CONNECTED BY HDMI...
My remote controls my LG sound bar with the Roku remote that came with the sharp Roku tv from best buy and I do not have HDMI inputs in my LG soundbar it’s only connected via the optic cable
LG Soundbars responds to LG tv commands for their volume. makes it easy when you have alike tv & Soundbar brands. Add to this that Sharp Roku tv oem remote uses the LG tv code set. So, the Roku Tv remote controls the LG Soundbar directly. Just a very convenient coincidence. I still stand by what I posted earlier.
We are having the same issue. We had an older samsung tv, a polk soundbar with no hdmi port connection option so used the optic cable port and used a roku stick plugged in the back and it paired with the soundbar with no issues. The lightening struck that tv and we had to get a new one. We got a Hisense with roku built in, it came with the roku remote that doesnt have the same options as our roku stick remote. We CANNOT get this to pair with the soundbar, we have tried everything. We also have Direct TV, that remote pairs just fine, but when we go to stream or watch live tv, every time we arrow down the volume on the sound bar goes wayyyy up. Thats the only way to get sound from the soundbar when using the roku remote. Im ready to unplug the soundbar and not use it, its turning into the biggest pain in the rear. Does anyone have a FIX??????
