Hisense Roku TV No Sound: How to Fix?

Having issues with no sound or audio not working on your Hisense Roku TV? Don’t worry; simple troubleshooting steps often fix this common problem. In this comprehensive guide, we’ll walk you through all the potential causes of and solutions for no sound on Hisense Roku TVs.

Causes of No Sound on Hisense Roku TV

Before jumping into solutions, let’s first take a look at some of the most common reasons you may be experiencing no audio from your Hisense Roku TV:

  • Faulty HDMI Cable Connection: If the HDMI cable connecting your Roku TV to an audio device like a soundbar or AV receiver is either loose, damaged, or connected to the wrong input/output, it can prevent audio transmission.
  • Incorrect Audio Output Settings: The audio settings on your Roku TV may be incorrectly configured for the source device you’re using. For example, if you’re trying to use a soundbar but the TV audio output is set to the internal TV speakers.
  • Needs a Software Update: Outdated software/firmware on your Hisense Roku TV can cause problems with audio not working properly. Checking for and installing any available updates may resolve no sound issues.
  • App/Source Audio Issue: The individual app or source you’re trying to use, like a streaming service or cable box, could have its own audio bugs. The problem may lie with the content source rather than the TV itself.
  • Soundbar Power Off: If you’re using a soundbar or other external audio device, ensure it is powered on and that any necessary cables are properly connected between it and the Roku TV.
  • TV Mute is Enabled: Something as simple as accidentally enabling the mute function on your Roku remote could prevent audio from coming through.
  • Faulty Speakers/Audio Hardware: In rare cases, the issue may be due to faulty audio components within the TV itself, like damaged or disconnected internal speakers.

 Some Quick Fixes to Try First

Before diving into more advanced troubleshooting, here are some quick and easy fixes to try out first that may resolve your Hisense Roku TV’s audio problems:

  1. Check TV Mute: Use the Roku remote to confirm the TV isn’t muted. Press the mute button on the remote several times to ensure it isn’t stuck.
  2. Check External Audio Device Connections: For soundbars, receivers, or other audio components, ensure all necessary cables are securely connected between the TV and the device.
  3. Confirm Source Audio: Try switching between different input source devices connected to your Roku TV, like a cable box or game console, to see if the audio works properly from at least one source. This can confirm where the issue lies.
  4. Restart your TV: Select Settings > System > Power > System restart from the Roku home screen menu to reboot your TV. Restarting can clear any software bugs causing audio problems.
  5. Check for Software Updates: Go to Settings > System > System update on your Roku TV to check if any software updates are available to install, which could resolve audio issues.
  6. Replace HDMI Cables: Swap out any HDMI cables connecting your devices to the Roku TV for new, high-speed HDMI cords to rule out cable problems.

Hisense Roku TV Sound Not Working: What to Do?

If you’ve tried the quick fixes above and are still experiencing no sound or audio issues on your Hisense Roku TV, follow these more in-depth troubleshooting steps:

Check if the Issue is Limited to One Device or Input

Determine if your Roku TV’s no sound problem only affects one connected device, like a game console or cable box, or if it has audio issues across all sources. This can help narrow down where the root cause lies.

Test different HDMI input ports by moving devices to different connections. Also, try built-in apps like The Roku Channel to see if they exhibit audio problems as well.

If the no sound issue appears isolated to just one device or input, then the problem likely stems from that source device rather than the Roku TV itself. You’ll need to troubleshoot the device’s audio connections and settings instead.

Restart Components and TV

If you still have no audio, try restarting your TV and any external components connected to it. Unplug devices like Blu-ray players and game consoles from power, wait 60 seconds, and plug them back in.

For the Roku TV, navigate to Settings > System > Power and select System Restart. After restarting, check if sound has returned when watching TV and content from source devices. Sometimes, a simple restart can resolve minor software glitches causing no audio.

Reset Audio Settings on the Roku TV

Update Roku TV Software

Hisense Roku TV System Update

Out-of-date software/firmware can contribute to audio not working properly on your Hisense Roku TV. Roku periodically releases system updates with bug fixes and performance improvements.

Go to Settings > System > System update > Check now to see if your TV has any pending software updates to download and install. This is an important step, as updating can resolve latent audio issues.

After the TV reboots, You can manually initiate a system update by going to Settings > System > Power > System restart > Update. Install any available updates that show up after restarting.

Inspect all Connections and Cables

Carefully examine all physical connections between your Roku TV, audio devices like a soundbar or receiver, source devices like a streaming stick or game console, and the HDMI cables between them.

Look for any loose connections, damaged cables, or incorrect input-output pairing. For example, ensure the HDMI cable from your Roku streaming stick is connected to an HDMI input on the TV rather than an output.

Try swapping HDMI cables for new ones, if possible, to rule out faulty cords. Also, test each device on different TV inputs to pinpoint connectivity problems. Proper cable connections are imperative for quality audio.


Test Speakers and Connections

Your audio malfunction may stem from hardware rather than software issues. Speakers within your Hisense Roku TV may have become damaged or disconnected.

First, visually inspect the internal speakers for any debris or damage. Next, play something with audio and close your ear to the speakers to listen for sound. Check both internal speakers in this manner.

If the speakers appear functional, the problem may be with loose speaker wire connections inside the TV’s housing. This requires opening up the TV cabinet to check connections. Only attempt if you are experienced with electronic repairs.

In many cases, faulty internal speakers or audio connections require professional service. Contact Hisense customer support for additional troubleshooting help if needed.

Factory Reset Roku TV

Be aware that a factory reset will remove all customized settings, installed channels, paired devices, and screen calibration. Make sure no important data is stored before resetting. Re-linking your Roku TV accounts and settings will be required after completing the reset process.
