If you're experiencing no sound on your Roku TV, the most common fixes are checking the mute button and ensuring sound isn't being sent to a powered-off external device. This guide walks you through every step to restore audio, from the simplest checks to a last-resort factory reset.
First, check for mute and external audio devices
The most frequent cause of no sound on your TV or speakers is accidentally pressing the mute button on your Roku remote. Press the mute button again to unmute and verify the volume is turned up to an audible level. If you have external audio devices like a soundbar, speakers, or headphones connected, unplug them to check if sound returns to the TV's built-in speakers. Sound may be routing to a device that is powered off or disconnected.
Confirm your Roku TV speakers are selected
Your Roku TV may have switched its audio output to an unavailable device. Navigate to Home > Settings > Audio and verify that "TV speakers" is chosen under "Audio Output." If another option is selected, change it back to TV speakers to restore sound to your television's internal speakers.
Restart your Roku TV to clear temporary glitches
Temporary software bugs can cause audio to stop working. Perform a system restart by going to Settings > System > Power > System Restart, or unplug the TV from the wall, wait 30 seconds, and plug it back in. This refreshes the system and often resolves sound issues caused by minor software errors.
Check the HDMI connection and input source
Ensure the correct input source is selected on your TV using the Input or Source button on your remote. If using an HDMI cable, verify it is firmly connected to both the Roku TV and the source device. Try a different HDMI port on the TV or replace the cable entirely to rule out a faulty connection. A loose or damaged HDMI cable can carry video but fail to transmit audio.
Adjust the digital output format and volume mode
Incompatible audio formats can silence your TV. Go to Settings > Audio and change the "Digital Output Format" to "Stereo" or "Auto" if it is currently set to a specific surround sound format your system may not fully support.
Enable ARC or eARC for external sound systems
If you use a compatible soundbar or receiver with an Audio Return Channel (ARC) or Enhanced Audio Return Channel (eARC) connection, ensure it is enabled. Navigate to Settings > System > Control other devices (CEC), highlight "ARC" (or "eARC"), and check the box. When a Roku TV is paired with Roku wireless speakers, the TV's built-in speakers are automatically disabled, so ensure those wireless speakers are powered on and properly connected.
Update your Roku TV software and check for app issues
Outdated software can introduce audio bugs. Check for and install any available updates by navigating to Settings > System > System Update > Check Now. If sound is only missing on specific channels or streaming apps, the issue might be isolated to that particular content provider or application. Test a different streaming channel to confirm whether the problem is app-specific.
Perform a factory reset as a last resort
If all other steps fail, a factory reset can resolve persistent audio issues. Go to Settings > System > Advanced System Settings > Factory Reset. Be warned: this erases all personalized settings, installed channels, and account information, returning the TV to its original state. Only use this option after exhausting all other troubleshooting steps.
