How To Fix An Insignia TV That Has No Audio Through The Speakers

The range of fixes you’ll need to employ to fix the sound on your television depends on the desired output of your audio. Firstly, here are the most common fixes for Insignia TVs that are struggling to output audio from their inbuilt speakers.

1. Check Your TV Settings

Technology can be unpredictable; one minute, you’re sitting back, relaxing, and watching your favorite program. The next, you’re staring at a silent screen that’s lost its audio. Sometimes there’s no rhyme or reason to this loss of audio – though commonly, human interference or updates can instigate changes within the settings.

Still, it’s easy enough to check your audio preference by following these steps:

  1. Press the menu button on your remote control.
  2. Go to the “advanced settings” and click the “audio” tab.
  3. Look at the selected audio output – it should be your TV speakers.

If the chosen output is not your TV speakers, you’ve found the culprit to your loss of audio. Click on the selected output and adjust to your TV speakers; your problem is solved.

2. Do A “Soft” Reset On Your Insignia TV

Conducting a soft reset is a good starting point for fixing audio issues with your system. Unplug your TV from the wall and wait for 60 seconds before reconnecting it and turning it back on. While your TV is unplugged, press and hold its power button for 30 seconds (this helps drain residual power, making the reset more effective).

It may sound simple, but doing a soft reset is often a great way to fix any issues with your TV; it takes minimal time and doesn’t affect your other settings. Still, if this doesn’t work, you can try several different solutions to restore the audio to your device.

3. Check The Mute Function

Another “it may sound obvious, but you’d be surprised how often it happens” fix is the mute function. You may assume that a TV in mute mode will display an icon somewhere on the screen, but this is not always the case.

Try pressing the mute button on your remote. Leave it for a few seconds and see if the sound returns. Repeat the process one more time to ensure that the mute function is not the issue.

4. Check That The Connection Cables Are Secure

Your television’s lack of audio might signify a loose cable preventing the proper transfer of sound. To identify whether or not this is a problem, turn off your device, check each connection cable, and then turn it back on.

If the cable ports are dusty, try unplugging each cable, cleaning it and its port with a dry cloth, and reattaching them.

Other Things You Should Check When Examining Your Cables:

  1. Ensure each audio cable is securely attached. Ensure they don’t wiggle, and check for damage to any wires or casings.
  2. Look for damage (or bends) in your power cable. A lack of sufficient power could mean your TV lacks the energy to function correctly.
  3. Ensure your TV cable and antenna are correctly connected.
  4. Ensure no external devices – such as headphones – are plugged into the audio output.

5. Alter The Audio Settings

If the external elements of your Insignia TV – such as cables and connections – then the problem could lie in the settings. To change the audio settings, follow these instructions:

  1. Press the menu button on your remote control.
  2. Select the “audio” option.
  3. Ensure your TV speakers are set to auto.
  4. Then, select “digital audio format / audio delay.”
  5. Change this format to PCM

After completing these steps, close the settings menu and restart your TV. If you use a service such as a TV box, you might have to go into their settings and change the format to PCM.

PCM – or pulse-coded modulation – is an audio decoder that assists audio streaming through your TV speakers. It helps to transmit audio signals smoothly and without loss of quality.

6. Restore Default Settings To The Audio And Video

If you don’t want to lose customization on your TV, try restoring the audio or video autonomously rather than the whole system. This way, you can undo any changes made to the audio settings while maintaining the customization of your overall system.

How To Restore Default Audio:

  1. Press the menu button on your TV remote.
  2. Go to the “audio” menu section.
  3. Select “reset audio settings.”
  4. Confirm you want to reset the audio and allow your TV time to complete this process.

How To Restore Default Audio:

  1. Press the menu button on your TV remote.
  2. Go to the “picture” menu section.
  3. Select “reset picture settings.”
  4. Confirm you want to reset the picture and allow your TV time to complete this process.

7. Restore Factory Settings

If all else fails, you can restore the factory settings to try and solve the issue. Here’s how to do that:

  1. Go into the settings menu.
  2. Select “system settings.”
  3. From the submenus, select “advanced system settings.”
  4. Once you’ve located this menu, select “Factory Reset Everything” and click ok.

Remember this option will delete any customization you have on your television. This means you’ll need to reinstall an app, reconnect to your Wi-Fi network, and set up all passwords from scratch.

8. Conduct A Hardware Reset On Your TV

If system resets failed to make a difference to your television’s audio output, you could instead try a hardware reset.

Before you start, ensure your Insignia TV is unplugged from the power outlet, and no electricity is going to your device. Then follow these steps to reset your hardware:

  1. Remove all of the cables from your television.
  2. Leave to stand for 30 seconds.
  3. Press and hold the “power” and “volume +” keys simultaneously for 60 seconds.
  4. Allow your TV to rest for five minutes.
  5. Reconnect all cables to the back of your television (leave the power cable until last.)

How To Fix An Insignia TV That Has No Audio Through The HDMI

Streaming audio through HDMI slightly differs from selecting the TV’s speakers as your audio output. Loose or dusty cables are a common factor that could cause either audio system to fail, but many other fixes are somewhat different for HDMI audio outputs.

In addition, you can restore factory settings to help clear any unwanted changes in your system, but they will likely return the audio to your TV speakers.

This means that once you conduct a factory reset, you will probably need to go into your settings and select the HDMI connection as your desired output.

1. Enable eARC or HDMI-CEC ARC.

The ARC – or audio return channel – feature allows you to send audio from your television to a receiver via a HDMI cable. This can simplify your wiring and help your audio transmit smoothly.

  1. Access the main menu and click on “settings.”
  2. Select the “audio” tab.
  3. Click on “HDMI-CEC device control.
  4. Enable “ARC/eARC.”

After following these steps, restart your TV to enable the ARC feature. If this doesn’t reinstate your sound output, you’ll need to check the settings.

2. Check The Output Is Set To HDMI

If eARC fails to bring back the sound to your television, checking the output will be your next best fix. To do this, follow these steps:

  1. Access the main menu and select “settings.”
  2. Click on the “audio” tab.
  3. Select “audio output,” then choose HDMI from the options provided.

3. Check The Device

Say you’re attempting to stream audio to a soundbar. In that case, there could be a problem with the hardware itself.

Check that your product is compatible with your television, test a different audio output on your TV, test if your external device is working by plugging it into another audio source, and check for any obvious faults or damage.

If there’s a problem with the external device you’re trying to connect to, you can run as many resets and settings changes on your TV as you like, but they won’t be able to fix the faulty hardware.

4. Contact Tech Support

Insignia tech support is your go-to expert when none of the listed fixes solve your problem. They may be able to provide instructions over the phone or deploy and technician to your home to rectify the issue.

When working with electronics, you must prioritize safety. If you don’t know how to fix something, leave it to the experts. Unless qualified, don’t try to take your TV apart or conduct any repairs by yourself.

Final Thoughts

There are many reasons why the audio could be failing on your Insignia TV. The most common is a change to the settings, loose connections, or your system requiring a reset. It’s always best to check your connections and conduct a soft reset before resorting to more impactful measures like restoring to factory settings.

Dirt and dust build-ups can present a problem, as well as faulty devices connected to your HDMI port. If you are still looking for the problem’s source, you can always contact Igsignia’s tech support for further advice.
