Sonos No Sound with Kogan Roku TV

You need both CEC (Consumer Electronincs Control) and ARC (Audio Return Channel) turned on in the settings menu.  Where these items are in the Settings menu will vary between model numbers.  If you can't find them, list your specific model number here.

Hi thanks for your reply. I would appreciate your help to set it up as I tried many options.

below my tv

Kogan 55" LED 4K Smart Roku TV - R94K

Bought 11/2023.

fire tv 4k max 2026 just bought.

thank you

My Amazon Firestick 4K Max works great on my Sony so it isn't likely to be your issue. 

Have you tried the Atmos test under the Firestick diagnostics section? Not near the tv to give you the menu path.

Bring up the Settings menu on the TV, go to Options, HDMI CEC.  Set HDMI CEC to On. Set HDMI ARC to On. Exit the menu.  If that doesn't complete the setup, you may need to unplug the TV and Beam from the wall socket and replug them in to force an HDMI handshake.

Hi mate thanks for answering. I tried multiple times and it asks me to connect fire tv on hdmi arc but Sonos is there.

hi thanks for answering. I tried multiple times different congratulations. Below photos of how it is now.

tried as you suggested to unplug and turn it off n on too, still the same issue. 
 

Hi ​@Romulorochabr 

Welcome to the Sonos Community!

I’m sorry to hear of this issue you are having with not getting any TV sound from your Beam. It sounds most frustrating!

Please try unplugging the TV from the power and disconnecting the Fire Stick. Plug the power for the TV back in - do you then get TV audio successfully? If so, then it appears there is a HDMI-CEC conflict causing the issue. With the link now made, you might then be able to plug in the Fire Stick (it does not need the ARC port - any HDMI port will do, though it may still need a higher-specification HDMI port than others, if available) and still get audio. If not, you may need to purchase a cheap CEC blocker to fit to the Fire Stick to resolve the issue.

If none of that works, however, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.
