Use a supported settings route
Roku documents choosing the sound mode from another appropriate app and returning, where the selected mode remains in effect. Follow the current instructions for the actual Roku product; TV and player settings can differ.
After returning, compare the same passage at a moderate level. Confirm the intended listening change rather than assuming that a menu selection established its audible result.
Retain the product limits
Available modes vary by model. If a mode never appears through the documented route, consult product support before inventing a hidden switch or factory-resetting the device.
A useful report names the Roku model, app and Star action, plus the route used to select sound mode. It keeps an app’s input handling separate from a hardware or programme-quality claim.
Questions answered
Does Star behaving differently prove the remote is broken?
No. Roku says some apps assign it another function.
Will every Roku offer the same volume modes?
No. Mode availability is product-dependent.
