Roku setup

[abkap39]

I have checked every connection and setting as well as changing HDMI ports the devices are plugged into. Regardless what I do, I can not get the soundbar, plugged into the arc port on a TCL tv, with a roku 4K+, brand new, to work no matter which HDMI port I use. I reset everything multiple times. Even unplugged the whole system, including the tv to give it a hard reset and I receive no volume output even if I turn the soundbar on with the remote and it shows powered on. I can switch the tv to internal speakers and have no issue with the sound. I really like the ROKU and have multiples connected on various tv's with a JBL and Cambridge Audio soundbars and have had no issues, I can not seem to get it to work with a nakamichi soundbar and surround sound. All firmware is up to date. I even attempted to reset to factory settings and redo the entire set up with no change. 

I'm extremely frustrated at this point and may have to return the ROKU. Please let me know if you have any further suggestions before I need to do this.  Thank you

Great to see you here in the Roku Community, @abkap39!

I understand you're having trouble getting your Roku device and Nakamichi Soundbar to work with your TCL TV via the ARC port. Let's get this sorted out!

Could you tell us more about:

• Which HDMI ports your soundbar and Roku device are connected to? Is your soundbar connected to HDMI ARC and your Roku device to a different HDMI port? Or is it the other way around?
• Where do you normally experience no volume on the soundbar? Is it only when streaming on Roku or even when on the regular TV while the Roku device is connected to it?
• Lastly, have you tried the same setup on a different TV? Or did you test a different soundbar on that TV with the same Roku device if it also encounters the same behavior? 

Let's keep the conversation going!

Best,
