Why does my Insignia TV have no sound?

Your Insignia TV has no sound because you have faulty or loose HDMI cables. This issue also happens if you’re using the wrong audio settings. And in other cases, glitches or bugs on the TV’s system cause this audio problem. 

Insignia TV no sound: 9 fixes

#1: Check if your TV is on mute

When you can’t hear anything from your Insignia TV…

It’s not always due to software or hardware problems. 

See, your device may simply be on mute without you realizing it. 

So before you go ahead and try to change anything on your TV… 

Ensure that it’s not muted. 

To do this… 

You can simply press the Mute button on your Insignia remote. 

Or increase the volume of your TV. 

And once you’ve ensured that your device isn’t on mute… 

Try to play a show or movie again to see if you can hear anything. 

Now, if your TV still has no audio, then proceed to… 

#2: Do a channel rescan

Are you streaming on any of your TV channels?

Then you should try to do a channel rescan if you still can’t hear anything. 

See, there might be a glitch with a specific channel on your TV.

And sometimes, all of them may even be affected. 

So you should conduct a rescan to refresh and update your TV channels. 

“I don’t know how to.”

Don’t worry. I’ve listed the specific steps you need to follow. 

With that…

Here are the steps to do a channel rescan: 

  1. Tap the Menu button on your Insignia remote. 
  2. Click Channels from the list of options. 
  3. Select Auto Channel Search.
  4. Click the Antenna option. 
  5. Wait for the process to finish.

Now, of course, not everyone watches through TV channels. 

So if you’re streaming through external devices like:

  • Roku. 
  • Apple TV.
  • Fire TV Stick.  

Then you should try watching on a different app or platform instead.

For example, if you’re currently watching on Netflix…

Try to play some videos on Youtube instead. 

And if switching the app fixed this issue…  

Then the problem isn’t your TV but the streaming platform you’re using. 

And in this case, you should contact the representatives of that particular app. 

But if switching to a different streaming platform didn’t fix your TV’s audio, then you should… 

#3: Power cycle your Insignia TV

Power Cycle Your Insignia TV

See, your TV may be glitching. Or overwhelmed with its ongoing tasks.

And when your TV can’t handle this load anymore… 

Different types of problems can occur. 

And that includes your Insignia TV not having any sound. 

However, don’t worry. 

It’s very easy to remove minor glitches and restart your TV system. 

All you need to do is power cycle your TV. 

Or unplug it from its power source before plugging it back again. 

Simple, right? 

So with that in mind, here are the…

Steps to power cycle your Insignia TV: 

  1. Unplug your TV from the outlet.
  2. Press and hold its power button for 30 seconds.
  3. Wait for 1 minute. 
  4. Plug it back into the outlet.
  5. Turn ON your TV. 

Now, try to play any channels or videos on your TV again. 

Still can’t hear the sounds of the show you’re watching? Then… 

#4: Check your HDMI cables

HDMI cables relay video and sound from your input device to your TV.

So if they’re loose or faulty in any way… 

You might lose the audio/video quality on your TV.

Or worse, they might even stop working. 

With that, it’s crucial to…

Ensure that your HDMI cables are in good condition:

  1. Unplug your HDMI cables from your TV. 
  2. Inspect them thoroughly. Check for any deformation, discoloration, or tears. 
  3. Check the connectors and ensure that all pins are in good condition.
  4. If you don’t find any issues, plug the cable into your TV again. 
  5. If your cable is faulty, replace it with a high-quality HDMI cable

Note: The same procedure applies if you’re using RCA connectors instead of HDMI cables.

#5: Ensure that your audio settings are set to “TV speaker”

See, you can connect your Insignia TV to external speakers or headphones. 

So it may be connected to a different audio output now…

And that’s why you can’t hear audio from your TV speakers. 

Now, if this is the case, you must set your TV to the correct audio output settings again. 

And to do that, here are the steps to… 

Ensure your TV is using its built-in speakers: 

  1. Turn ON your TV.
  2. Tap Home on your remote. 
  3. From the menu, select Advanced settings.
  4. Go to the Audio Tab. 
  5. Set your audio output to TV speakers.

Now that you’re using the right audio output…

Try playing any show or movie again to check your TV’s sound. 

“I still can’t hear anything.”

In that case, you should proceed to… 

#6: Change your TV’s audio format

Your TV is now using the right audio output…

But it may still be using the wrong audio format.

Now, don’t worry, even if you don’t know what this refers to. 

Because really, it’s effortless to…

Set your TV to the right audio format: 

  1. Tap Menu on your remote control.
  2. Select Audio. 
  3. From the list, tap Digital Audio Format/Audio Delay. 
  4. Select Audio Format. 
  5. Ensure that this setting is set to PCM. 

Now, before you try to test your audio again… 

You need to change another setting if you’re using external input devices to stream on your TV.

See, streaming devices like Apple TV or Roku also have their own audio settings. 

So you need to set their audio to PCM or Stereo as well.

Now, it’s worth noting that the exact steps for this process depend on your device’s model. 

But to give you an example of how you can generally do this… 

Here’s how you change the audio format of an Amazon Fire TV Stick:

  1. Go to Settings. 
  2. Select Display & Sounds from the icons. 
  3. Click Audio. 
  4. Go to Surround Sound. 
  5. Select Stereo. 

Note: You can choose either Stereo or PCM as the audio format of your streaming device. 

So use these steps as a guide to changing the settings on your gadget.

And once you’ve corrected both your TV and input device’s audio format… 

Check if the problem has been fixed.

#7: Reset audio settings 

If you still can’t hear anything on your TV…

Some of your audio settings may still be set incorrectly. 

Now, with all the different audio menus there are on your device… 

It’s time-consuming to check them all individually. 

That’s why to save time, effort, and energy…

You should reset your TV’s audio settings instead. 

So you can bring all of them to their default states in just 1 single process. 

With that being said, here’s how you can… 

Reset your Insignia TV’s audio settings:

  1. Press Home on your remote. 
  2. From the window that appears, tap Audio. 
  3. Select Reset Audio Settings. 
  4. Confirm the action. 
  5. Wait for the process to be completed.
  6. Restart your TV. 

#8: Factory reset your Insignia TV

Your TV’s audio problem is really keeping up a fight, huh? 

But don’t worry. You still have a hidden card up your sleeve.

Now, are you familiar with the term factory reset? 

See, that’s what you need to do to your device now. 

Simply speaking, a factory reset is the king of all resets you can do on your TV. 

Because by doing it, you’ll remove all your data and information from your device. 

And you’ll also return all your TV settings to their default states, including the ones for your:

  • Audio. 
  • Channels.
  • TV Picture. 

Now, if you’re wondering…

“Is it necessary to reset everything if I just need to fix my audio?”

Yes, sometimes it is. 

As mentioned, this reset deletes all saved data and contents from your TV.

But really, it’s not just limited to those.

See, if your device currently has glitches or bugs attached to its contents…  

You’ll also remove them through the factory reset.

And if they’re the ones causing this stubborn issue on your Insignia TV…

That means your audio will work again after this process.

Now, I know all of these sounds techy and all…

But don’t worry. The steps to factory reset your Insignia TV are extremely easy to follow.

Just a few buttons on your remote. And a little touch of patience. 

With that being said…

Here’s how you can factory reset your Insignia TV:

  1. Click the Home button on your remote control.
  2. Navigate to the Settings page.
  3. From the list of options, tap Device & Software.
  4. Tap Ok.
  5. Select Reset to Factory Default. 
  6. Wait for the process to finish. 

Generally, this reset doesn’t take too long to load. 

And the longest you’d need to wait would be 15 minutes or so.

So once your TV turns ON again… 

Try to play some shows or videos to check if your TV’s audio is already working. 

#9: Contact professionals

Unfortunately, you can’t fix all problems at home.

See, your TV speakers may be faulty or broken.

Or the device might be experiencing some serious hardware problems. 

And either way, you need to contact professionals to fix this issue. 

Now, if it hasn’t been a year since you bought your TV yet…

I highly recommend contacting Insignia themselves. 

Because not only do their representatives know your TV the best…

You might not even have to pay for anything if you still have a warranty for your TV. 

With that in mind, here’s how you can… 

Contact Insignia’s support team:

  • Send them an email.
  • Call them at 1-877-467-4289. 

Now, if your TV is no longer under warranty… 

You may also choose to contact reliable local technicians around you.

As sometimes, letting them fix your TV would be cheaper and faster. Compare that to sending your device back to Insignia.
