1. Check Mute Functionality

When troubleshooting sound issues with your Insignia TV, it’s crucial to start with the basics. The first step is to ensure that the TV’s audio isn’t accidentally muted.

This can happen either through the remote control or directly on the TV itself. Locate the mute button on your remote control or use the TV’s onboard buttons to unmute the sound.

This straightforward action might swiftly resolve the problem and bring back the audio you’ve been missing.

2. Verify Remote Control

If you primarily control your TV’s volume using a remote, take a moment to verify the remote’s functionality. Check if the remote is working correctly by pointing it at the TV and pressing various buttons.

Sometimes, remote control issues or depleted batteries can disrupt sound output. Replace the batteries if necessary, and make sure there are no physical obstructions between the remote and the TV.

A functional remote is essential for hassle-free volume control.

3. Inspect Cables

The next step is to inspect all the cables connected to your Insignia TV, including both audio and video cables. Ensure they are securely plugged into their respective ports.

Loose or disconnected cables can lead to sound problems, so a quick check can make a big difference. Pay special attention to RCA, or optical audio cables, depending on your setup.

If any cables appear damaged, consider replacing them to ensure a reliable connection.

4. Replug the HDMI Cable

For users utilizing HDMI connections to link their Insignia TV to external devices like gaming consoles or Blu-ray players, a loose HDMI cable connection can be a culprit behind sound issues.

To address this, simply unplug the HDMI cable from both the TV and the connected device. Then, securely reconnect it to ensure a stable connection.

5. Try a Different HDMI Cable

If the previous steps haven’t resolved the issue and you suspect problems with the HDMI cable, consider swapping it out with a known working HDMI cable.

Using a different cable can help identify whether the original cable was faulty and causing the sound problem. This simple test can rule out cable-related issues and ensure you’re using a reliable connection method.

6. Switch HDMI Ports

If you’re using HDMI connections, consider trying a different HDMI port on your TV. Sometimes, a specific HDMI port may be causing the sound problem.

Switching to another port can help determine whether the issue is specific to that particular input.

7. Perform Power Cycle/Soft Reset

If the sound issue persists, try a power cycle or soft reset.

  • Begin by unplugging the Insignia TV from its power source.
  • While it’s disconnected, press and hold the power button on the TV itself for approximately 30 seconds.

This action helps discharge any residual power and reset the TV’s internal components.

Afterward, plug the TV back in, turn it on, and see if the sound has returned. This step can often resolve minor software or hardware glitches causing the sound problem.

8. Adjust Audio Settings

Now, let’s delve into the TV’s audio settings. Access these settings through the on-screen menu, which often involves pressing the “Menu” button on your remote control.

Once you’ve entered the menu, navigate to the audio settings section. Here, confirm that the correct audio output source is selected. Depending on your setup, this might be HDMI, RCA, or another option.

Also, ensure the volume is appropriately adjusted to a level that allows you to hear the sound clearly. Accurate audio settings play a vital role in restoring and optimizing your Insignia TV’s sound quality.

Additionally, if you have the option, consider switching the audio output mode to “PCM” or “Stereo.”

Click on Audio > Digital Audio Format / Audio Delay > Audio Format > PCM.

This selection can help resolve any potential sound format conflicts, ensuring compatibility with various audio sources and devices.

9. Turn on ARC/eARC

After trying the above audio settings try enabling ARC/eARC (Audio Return Channel/Enhanced Audio Return Channel) on your Insignia TV. It often resolves no sound problems.

It will establish a proper connection between your TV and soundbar through HDMI ARC/eARC ports and enable the HDMI CEC Device Control along with eARC if supported,

Here are the steps on how to turn on ARC/eARC on your Insignia TV to resolve no sound issues:

  • Connect your TV and soundbar using an HDMI cable, ensuring it’s plugged into the ARC/eARC ports.
  • On your TV remote, press “Menu.”
  • Navigate to “Settings” > “Display & Sounds” > “External Inputs.”
  • Select the HDMI port connected to your soundbar.
  • Under “HDMI CEC Device Control,” choose “On.”
  • If your TV supports eARC, turn it “On” under the “eARC” option.
  • Save your settings by pressing “Exit.”

10. Check for External Audio Devices

Sometimes, other devices connected to your TV can interfere with the sound output. If you have Bluetooth headphones, AirPods, or any other wireless audio devices paired with your TV, disconnect them temporarily.

This can help eliminate potential conflicts and ensure that the TV’s audio is directed to the appropriate output, such as its built-in speakers or a connected soundbar.

11. Check Attached Devices

Make sure any external devices connected to your Insignia TV, such as cable boxes or gaming consoles, are powered on and functioning correctly.

Sometimes, sound issues can stem from the external device itself, so it’s essential to confirm their operational status.

Next try resetting the hardware, to do so:

Unplug all cables connected to the TV and wait for a few minutes. During this time, any residual power dissipates, and the TV essentially performs a soft reset.

Afterward, reconnect all cables, ensuring they are properly seated in their respective ports.

14. Update Firmware

Try updating the firmware. It can resolve software-related audio problems, as manufacturers often release patches and improvements.

Here’s how to update your Insignia smart TV:

  • Then go to Settings > Device & Software > About > Check for Updates

15. Perform Factory Reset (as a last resort)
