As one of the most popular streaming devices on the market, Roku TV is known for its high-quality picture and sound. However, like any other electronic device, it is not immune to glitches and malfunctions. If you are experiencing issues with the sound on your Roku TV, there could be several reasons why this is happening. In this article, we will explore some of the most common causes of sound problems on Roku TV and what you can do to fix them.

The Volume Is Too Low or Muted

One of the simplest explanations for why the sound is not working on your Roku TV is that the volume is too low or muted. Make sure that the volume on your TV is turned up and that it is not muted. You can use the volume buttons on your remote or the Roku mobile app to adjust the volume.

The TV Speakers Are Not Selected

Another reason why the sound may not be working on your Roku TV is that the TV speakers are not selected as the audio output. If you have external speakers or a soundbar connected to your Roku TV, the audio may be set to output through those devices instead of the TV speakers. To fix this, go to Settings > Audio > Audio mode and select “Stereo” or “Surround sound” to enable the TV speakers.

The HDMI Cable Is Not Connected Properly

If you are using an HDMI cable to connect your Roku TV to another device, such as a cable box or gaming console, the sound may not be working because the HDMI cable is not connected properly. Make sure that the HDMI cable is securely plugged into both the Roku TV and the other device. If the HDMI cable is damaged or faulty, try replacing it with a new one.

The Audio Settings Are Incorrect

The App or Channel Has Sound Issues

Try closing the app or channel and reopening it to see if that resolves the issue. You can also try uninstalling and reinstalling the app or channel to see if that fixes the problem.

The TV Firmware Needs Updating

Outdated firmware can sometimes cause sound problems on your Roku TV.

The TV Is Too Far Away from the Router

If you are using a wireless internet connection to stream content on your Roku TV, the sound may not be working because the TV is too far away from the router. Move the TV closer to the router or try using a wired connection instead to see if that improves the sound quality.

The TV Speakers Are Damaged or Broken

If none of the above solutions work, the sound problems on your Roku TV may be caused by damaged or broken TV speakers. In this case, you may need to contact the manufacturer or a professional repair service to have the speakers repaired or replaced.


There are several reasons why the sound may not be working on your Roku TV, but most of them can be easily fixed by checking the volume, audio settings, and connections. If you are still experiencing sound problems after trying these solutions, it may be time to seek professional help.
