On the Roku go to Settings › Remotes & devices › Remotes, select your remote and choose Set up remote for TV control. The Roku plays music and asks whether it stopped when it tried to mute the TV; answer the prompts until it finds the right code. This needs a voice remote. Simple remotes for Roku players have no TV buttons.
- Open remote settings
- Start setup
- Answer the prompts
Set up TV control
- Press Home, then open Settings › Remotes & devices › Remotes.
- Select your remote and choose Set up remote for TV control.
- Point the remote at the TV and follow the prompts. The Roku detects the TV brand over HDMI where it can and tests volume and power codes.
- If the TV brand is wrong or not detected, enter it by hand when asked.
On a Roku TV none of this is needed. The remote controls the TV directly because the Roku is the TV.
Why the buttons stopped working
- The remote was re-paired or replaced. TV control is stored per remote. Run the setup again.
- Something blocks the TV’s infrared sensor. Volume and power use infrared even on a wireless voice remote, so the remote must point at the TV for these buttons.
- Weak batteries. Navigation can keep working while the stronger infrared signal fails.
- A soundbar or receiver handles the sound. Set the TV to pass volume commands on through HDMI‑CEC, or run setup again and choose the audio device’s brand.
- Your TV only accepts part of it. Roku notes that with some TV models the remote can control volume but not power.
Voice commands for volume use a different route
Saying “turn the volume up” does not use infrared. The Roku sends the command to the TV through the HDMI cable (HDMI‑CEC). If voice volume fails while the buttons work, turn on HDMI‑CEC in the TV’s settings. It is called Anynet+ on Samsung, SimpLink on LG and Bravia Sync on Sony.
Controlling volume from your phone
A phone has no infrared, so a remote app controls volume over the network instead. On a Roku TV this works directly. On a Roku player it depends on the TV accepting volume over HDMI‑CEC. If the TV is a smart TV on your Wi‑Fi, Kliky can also connect to the TV itself and control its volume and power as a second device.
