Thank you for joining us here in the Roku Community, cart!
I'd be happy to suggest some steps to help you control the volume buttons using your Roku remote. I appreciate you for reporting this to us.
If the volume buttons on your remote have stopped working entirely, try to update your Roku device to the most recent software by navigating to your Home screen. Scroll up or down to select Settings > System > System update > Check Now
Confirm the dialogue box to proceed with the download and installation. Note that your Roku player will automatically download the latest software the next time when it checks for an update. After the Roku player finishes restarting, if TV control has not been restored, set up your remote for TV control again by doing the following:
- Navigate to Settings
- Select Remotes & devices
- Select Remotes followed by your remote
- Select Set up remote for TV control
Our FAQ provides additional information and complete steps to set up your voice remote to control your TV.
In addition, you may also visit our support article related to the following: Why is my Roku voice remote not controlling power and volume on my TV?
Let me know how it goes!
Best regards,
