Every time you have a problem with your Insignia TV, you can always count on a soft reset to resolve it most of the time. As such, performing this troubleshooting trick is advisable whenever you use your problematic Insignia TV with no sound.
Since most Insignia TV sound problems occur due to minor system bugs and errors, the soft reset is a practical way to deal with it. After all, this action lets your Insignia TV shut its system down to correct these bugs and errors after a reboot sequence.
You can eliminate other possible causes of sound problems since shutting down your Insignia TV with a soft reset clears cached memory. It’s an excellent way to deal with corrupt app data and files causing system malfunction on your Insignia TV.
Also, if you hold your Insignia TV’s power button during the soft reset, you can drain its residual electrical charges. With this, you can tackle all possible root causes of your Insignia TV’s sound problem and restore it after it reboots from the soft reset.

Step 2: Unplug your Insignia TV’s power cable from the wall outlet. |
Step 3: Wait 60 seconds so your Insignia TV can shut down its system completely. Note: You can also conduct a power cycle while you wait by holding its physical power button for 30 seconds. Doing so will drain its residual electrical charges, correcting minor errors that may cause sound problems. |
Step 4: Plug your Insignia TV’s power cable into a wall outlet to turn it on. Note: After plugging it into a wall outlet, you can press the power button if your Insignia TV doesn’t turn on automatically. |

Believe it or not, this aspect is often the simplest thing that many Insignia TV users find easy to overlook: the mute function.
It’s common for most people to mute their TVs unintentionally due to accidental remote button clicks. It can happen if someone happens to sit on the remote control or you have kids around who like to play with it occasionally.
Assuming there’s a system or device error whenever there’s no sound on their Insignia TV is very easy, but checking the volume is actually the most basic fix.

If you connect input devices to your Insignia TV, you must check their cable connections to ensure that audio signals are transmitted correctly. Otherwise, you might suffer from crackling audio, choppy and stuttering playback, or no sound on your Insignia TV.
The audio cables you use to connect your Insignia TV with an external input device are crucial for ensuring good-quality sound. Thus, they can’t generate sounds if the audio signals can’t be transmitted via the cables.
And like your Insignia TV and input device, these audio cables must also be in tip-top shape to perform well. Ensure they fit their respective ports, as a loose connection is the most common cause of Insignia TV sound problems.
Moreover, looking into your Insignia TV’s power cable would be best since it’s crucial for making the device work correctly. If your Insignia TV doesn’t receive sufficient electricity, hardware problems causing sound to stop working may occur.
Step 1: Turn off and unplug your Insignia TV from the wall outlet. |
Step 2: Unplug the cables from your Insignia TV’s back panel. Note: This includes your Insignia TV’s HDMI cables, RCA connectors, Auxiliary cords, and the power cable. |
| Step 3: Wait 10 seconds and plug the cables into your Insignia TV. Note: All cables must be snug to prevent a loose connection from causing sound problems. Replace any cable with visible signs of damage. |
Step 4: Plug your Insignia TV’s power cable into a wall outlet to turn it on. Note: After plugging it into a wall outlet, you can press the power button if your Insignia TV doesn’t turn on automatically. |

Your Insignia TV may not be producing a sound due to incorrect audio output settings. As such, we recommend changing your Insignia TV’s sound configuration to fit the content you’re playing on its display screen.
First ensure your Insignia TV’s speakers are enabled when playing audio natively on the device. Otherwise, you must change the selected audio output if connecting an audio device, like a Soundbar or wireless speaker, to your Insignia TV.
This way, your Insignia TV can play the correct audio from the input source, which should fix the sound problem. It’s important to note that you might need to manually change the audio output on your Insignia TV whenever you switch input sources.
However, some Insignia TVs allow selecting a default input source, so you don’t have to set it up every time. Using the same default input source on your Insignia TV can save you more time since you don’t have to keep changing its audio output.
Step 1: Go to your Insignia TV’s settings menu. |
Step 2: Click Displays & Sound. |
Step 3: Scroll down to Audio Output. |
Step 4: Turn on the TV Speaker if you don’t have any external audio devices Note: Turn this off to connect a Soundbar to your Insignia TV. |
Step 5: Go to Digital Audio Format. |
Step 6: Select PCM if you have external audio device. Note: Keep it at Auto if you only use your Insignia TV’s built-in speakers. |
Step 7: Return to your Insignia TV’s settings menu and click Device & Software. |
| Step 8: Select Restart to reboot your Insignia TV and apply the changes to its sound settings. |
FIX 5. Restore your Insignia TV’s factory settings

Sometimes, changing your Insignia TV’s configurations or rebooting its system isn’t enough to fix the sound problems, so the last resort would be a factory reset.
A caveat, though, is it wipes your Insignia TV and restores its initial settings—like how it was when you bought it. Since your Insignia TV had no sound problems when it was new, reverting it to that initial state should fix the issue.
Additionally, the factory reset deletes corrupt data and malware inside your Insignia TV’s system memory. Therefore, this method is excellent if your Insignia TV suffers from malware or viruses.
Be reminded that doing a factory reset also removes your installed apps and user accounts, so you must redownload and re-enter them after setting up your Insignia TV again.
WARNING: A factory reset should not be undertaken lightly. Secure a copy of your essential files and TV preferences, as the process will delete them all in one stride.
| Step 1: Turn off and unplug your Insignia TV from the wall outlet. |
Step 2: Hold your Insignia TV’s Power button. |
| Step 3: Plug your Insignia TV into the wall outlet while you hold its Power button. |
Step 4: Release the Power button once your Insignia TV turns on. |
| Step 5: Press the Power button to highlight the “Wipe data/factory reset” option and hold it down to select it.  |
Step 6: Select Yes to restore your Insignia TV’s factory settings. |
| Step 7: Select “Reboot system now” to restart your Insignia TV once the data wipe is complete.  |
| Step 8: Wait while your Insignia Fire TV reboots its system and proceed to the on-screen setup.  |

Resetting the sound settings is an ideal solution if the problem with your Insignia TV’s was due to prior changes made to the system settings. Thus, this action will restore the default sound configurations on your Insignia TV.
Unfortunately, you can’t reset all Insignia TVs’ sound or video settings since they have different menus and operating systems. As such, you must manually change the configuration on Insignia TVs without a sound or video settings reset option.
| Step 1: Go to your Insignia TV’s settings menu. |
| Step 2: Click Displays & Sound. |
Step 3: Go to the Picture Settings and Sound Settings menus. |
| Step 4: Click the Reset option under both settings menus if available. Note: You can change the configuration under these settings menus if there’s no reset option. Keep changing their configuration until you fix the sound problem on your Insignia TV. |

Software or firmware aside, you can conduct a hardware reset on your Insignia TV to let it correct the problems with its components and accessories. This action goes beyond the traditional power cycle process, making it ideal for hardware issues like overheating.
However, the hardware reset will only help fix the no sound issue if your Insignia TV’s components already have physical damage. For instance, doing this step is pointless if its built-in speakers are broken.
As such, performing a hardware reset is excellent at determining if your Insignia TV has damaged components.

| Step 5: Reconnect its cables. |
| Step 6: Plug your Insignia TV’s power cable into a wall outlet to turn it on. Note: After plugging it into a wall outlet, you can press the power button if your Insignia TV doesn’t turn on automatically. |
