Welcome to the Roku Community, @LosGatos!
We'd be happy to be of assistance here and help you connect to the right support regarding the audio issue you've observed inside the Cinema Box app.
Since this is an isolated case involving the Cinema Box app exclusively, we strongly advise that you contact their Support team for further assistance and clarification, as they are responsible for the contents available inside their app.
Please be advised that the majority of content on the Roku platform comes from streaming channels maintained and updated independently by the channel's provider.
We hope you find this information helpful.
Best regards,
