Audio does not work for any streaming channel. Roku System sounds work fine.
I verified that the issue is with the Roku set up by removing the Roku and using the smart TV features. Both the internal and the Sonos beam worked. But when I switched back to Roku only Roku System sounds worked.
Can you please provide us with more specific information about the issue you are experiencing? Do you encounter any error messages? Are all the other streaming channels operating normally? How long has the issue existed and what troubleshooting done to resolve the issue?
With detailed information, we will be able to assist you better.
