However, there are instances when Hisense TVs encounter issues like no sound or inconsistent volume levels. In rare cases, the Hisense TV sound keeps changing on its own (cutting in and out) while streaming.

Typically, this issue is caused by incorrect audio settings, outdated TV firmware, or problems with external devices. You can easily resolve the sound issue on your Hisense TV by following the troubleshooting steps outlined in this guide.

How to Fix Hisense Smart TV Sound Keeps Changing Issue

Below are some effective troubleshooting steps to help you resolve volume issues on your Hisense TV.

Restart Hisense Smart TV

• If the volume on your Hisense TV is fluctuating automatically, it might be due to a temporary glitch or firmware issue. A simple restart of your Hisense TV could resolve the problem. After restarting, check if the sound functions normally.
• If the sound is still unstable, try manually power cycling the TV. Unplug the power cord from the wall outlet, wait a few minutes, then reconnect it.

Check External Devices and Cables

• Loose or improper cable connections of external devices can lead to audio problems. Ensure that all cables from external streaming devices are securely connected to the TV.
• If you’re using external audio devices, such as a soundbar, verify that the connections are correct and that the sound settings on your Hisense TV are properly configured.

Try Playing Other Content

• In some cases, the streaming application might cause the issue. Try playing different content from the same app or switching to another app to determine the source of the problem.
• Close the current app and ensure it is no longer running in the background. Then, open the same or another app and try playing new content. If the sound works without issues, the problem may lie with the previously played content or app.

Check the Hisense TV Remote

• Volume problems on the Hisense TV can also arise from remote control malfunctions.
• Start by checking if the TV has been muted, especially if you’re experiencing muffled or no sound. Next, ensure that the volume buttons on the remote are not stuck. You can also try resetting the Hisense TV remote.
• If the remote hardware is damaged, you may need to either repair or replace it to resolve the issue.

Update the TV Firmware

Keeping your TV’s firmware up-to-date is essential for uninterrupted streaming and optimal performance. Follow these steps to update your Hisense TV and eliminate sound issues:

• Hisense Android & Google TV: Go to the Home Screen → Settings → Device Preferences or System → About → System update → Update now.
• Hisense Fire TV: Navigate to Settings → My Fire TV → Install Updates.
• Hisense Roku TV: Open the Settings app → System → Software Update → Check Now → Update Now.

Reset the Audio Settings

While updating the firmware resolves many issues, if the problem persists, try resetting the audio settings on your Hisense TV. This will only reset the audio configuration without affecting other data on the TV.

1. Press the Home button to open the Home Screen.

2. Go to the Settings section.

3. Scroll down and select Advanced System Settings.

4. Tap the Factory Reset option.

5. Choose Reset TV Audio or Picture Settings and press the Play or Pause button three times.

Factory Reset the Hisense TV

If the sound continues to fluctuate on your Hisense TV even after attempting the troubleshooting steps, a factory reset may be necessary. Keep in mind that, unlike an audio reset, a factory reset will erase all data, including installed apps and channels. After resetting, you’ll need to set up the TV from scratch.
