Roku Audio Not Working (No Sound/Not Sync With Video)

Roku systems are designed to make video streaming comfortable and straightforward. Despite the benefits of a Roku system, some users have reported common audio issues. Generally, users can resolve sound problems through the Roku device’s interface.

If the audio on your Roku device is not working, a hard reset can restore functionality. If that fails, try changing your device’s audio settings to improve the sound quality. Alternatively, if you are using a wired Roku system, you may want to consider replacing the HDMI cord.

I’ll clarify why your Roku audio isn’t working correctly in this post. Additionally, I will have troubleshooting methods to assist you in resolving your problem.

Roku Audio/Sound Troubleshooting

To begin, determine if the audio failure affects the entire system or a single channel. Consider testing all of the platforms and applications on your Roku device to determine if additional troubleshooting is necessary.

If you’re experiencing poor audio performance, you’re most likely having Wi-Fi problems. The best way to begin troubleshooting is by determining the frequency of the Wi-Fi signal. To assess the strength of your Internet connection, navigate to your device’s “Network” menu. If your signal strength is inadequate, increasing it would return your audio to its optimum state.

Consider the following techniques for increasing the Wi-Fi signal strength:

  • Decrease the distance between the router and the Roku system.
  • Increase the range of your Wi-Fi network by adding an extender.
  • Reposition the television.

Suppose your Wi-Fi is strong, but your Roku device’s sound is not working properly. In that case, you can resolve the issue by restarting the unit or updating the system’s software. For severe sound delays, a factory reset is the best troubleshooting method.

Before proceeding with any further troubleshooting steps, perform the following steps to reboot your device:

  1. On your Roku remote, press the “Home” button.
  2. Choose “Settings.”
  3. Select “System.”
  4. Choose “System Restart.”
  5. Highlight the Restart button.
  6. Select “Okay.”

Suppose your Roku machine is not responding. In that case, use your Roku remote to conduct the necessary steps to restart the device:

  1. Hit the “Home” button five times.
  2. Push the upward arrow one time.
  3. Press “Rewind” twice.
  4. Immediately push the “Fast Forward” button twice.

Following that, the Roku system will reboot in approximately three seconds.

How To Upgrade the Software on a Roku Device

If a restart does not resolve the issue, the issue may be with your software. If your sound problems persist, you should update your machine using the following steps:

  1. On your Roku remote, press “Home.”
  2. Pick Settings by scrolling up or down.
  3. Navigate to “System” and enter its menu.
  4. Locate “System Update” and select it.
  5. Choose “Check Now” to perform a manual upgrade check.

Suppose an upgrade is required for your device or activated apps. In that case, it will be immediately downloaded and installed, and your Roku will restart. Allow this process to complete itself before resuming use of your Roku computer.

How To Do a Factory Reset on Your Roku

If restarting and upgrading your system does not resolve your sound problems, try the following steps:

  1. Push the Home button.
  2. Go to the “Settings” menu.
  3. Hit “System” using your remote.
  4. Select “Advanced System Settings.”
  5. Choose “Restore to factory settings.”
  6. Reset everything to factory defaults.
  7. Adhere to the on-screen directions from your device.

Alternatively, you can press and hold the Roku device’s “Reset” button for at least ten seconds. Upon completion, ensure that you reconfigure the system with your desired settings.

Roku Audio/Sound Not in Sync With Video

Suppose your Roku audio is not in sync with the video. In that case, the problem may be with the wire. Consider buying a new cable if you find any fraying or damage to the cord. This method will usually resolve the matter.

If the wire is not the problem, the more likely culprit is your sound system. If you’re using an external sound system, verify that it’s Roku-compatible. If not, it is recommended that you use the built-in speakers on your television.

Suppose you’re using a Roku unit that isn’t connected to a wire or has an external sound system. In that case, the channel on which you are currently viewing is likely having slight issues.

Remove every channel that is experiencing a sound delay from the Roku home screen. After that, reboot your system. Once it has loaded, re-add the channel and attempt to play a video. If the problem continues, you’ll need to make changes to the Roku software.

Additionally, it is recommended that you disable game mode on your television if it is available.
