Sound issues when watching or listening to something on your Insignia TV can be frustrating. Several factors, such as muted audio, low volume, wrong audio settings, and incorrect cable connections, can cause these sound problems.
Luckily, you can troubleshoot and fix most of the sound issues affecting your Insignia TV at home. Some solutions you can try are unmuting your TV (or connected devices), increasing the volume, power cycling your TV, and troubleshooting your connected speakers.
Below is a detailed look at various issues that could be causing the sound issues, how to troubleshoot them, and various solutions to help fix them.
Basic troubleshooting tips
If your Insignia TV is experiencing sound problems, try the following simple troubleshooting solutions:
- Check that you have not pressed the mute button on your remote control.
- Increase your TV’s volume – the volume might be too low that you cannot hear any sound.
- Increase the volume of your external speakers.
- Check that the audio you are trying to play has sound—it could be that the channel, video, or audio file you are playing does not have audio.
If these troubleshooting steps fail to work, you can try the following advanced solutions:
1. Select the right audio output system
Does your Insignia TV have sound but no audio? You may be using the wrong audio system for your audio output.
This is a common problem that can occur if you use several external audio systems to play sound on your TV. For example, you could be trying to play audio on your external speakers, but your TV is connected to wireless headphones or other Bluetooth devices.
Therefore, before trying other solutions, connect your TV to the right external audio system. In addition, you should check your TV’s Bluetooth connection to ensure it has not connected to rogue Bluetooth speakers or wireless audio devices.
2. Check on your cables
Cable issues can also cause insignia TV sound problems. These can range from loose or wrongly connected audio cables to damaged or faulty cables.
To fix the sound problems, check that all audio cables are firmly connected to your TV, the audio source device, and the external audio system. In addition, ensure that the cables are all connected to the right ports.
Secondly, you should examine all your audio cables for any signs of damage; faulty audio or HDMI cables can cause poor (or no) sound issues. Therefore, if you suspect any damage to your cables, switch them out with new ones and check if the problem has been resolved.
3. Check your TV’s audio settings
The wrong audio settings could be causing your Insignia TV’s sound problems. For example, enabling the “auto volume” feature could cause low volume, while selecting the wrong audio output source could cause no sound issue.
To fix the problem, go to your Insignia TV’s audio settings and turn off the auto volume feature. This will allow you to adjust the volume with your remote or TV audio buttons.
Secondly, select the right audio output option from the settings. For example, set your TV speakers to “On” if you are playing audio through the TV speakers or to “Off” if you are playing sound through a connected device, such as wireless speakers.
Lastly, you can reset your Insignia TV’s audio settings. Doing this will erase all custom settings you have made and return them to the factory defaults.
4. Check that your speakers are working
If your TV does not sound, the speakers could be faulty. Therefore, try troubleshooting your speakers before you attempt more solutions.
If playing sound through your TV speakers, you can test them by connecting headphones to the audio auxiliary (headphones port). If you hear any sound on your headphones, your TV speakers are faulty and need repairs.
According to some Insignia TV owners on Reddit, simply plugging and unplugging your headphones in the auxiliary port can fix no sound issues on your TV.
If you use an external sound system, you can troubleshoot it by connecting your TV to another system, such as wireless headphones or Bluetooth speakers. If you hear any sound, your speakers might be the issue, and you need to have them checked by a technician.
5. Power cycle your TV
Sound issues on your Insignia TV can be caused by bugs or software glitches in your TV. Fortunately, you can fix most of these issues by power cycling (soft resetting your TV).
To do this:
- Turn off your Insignia TV.
- Unplug your TV’s power cord from the electrical outlet or extension cord.
- Press and hold the TV’s power button for about 15 seconds.
- Wait about 1-2 minutes, then plug in your TV and power it on.
6. Reset your source device or external audio system
Your sound issues could also be caused by bugs or glitches in the audio source device (for example, DVD player, TV box, or streaming box) or the external audio system (sound bar, home theatre system, or sound bar). Resetting these devices can help to fix these sound problems.
Some of these devices come with hard reset buttons (usually at the back panel) that you can use to reset them. You can also perform a soft reset by power cycling them to clear software bugs and other glitches causing sound problems.
7. Update your TV software and firmware
Sound issues can also be caused by outdated software or firmware on your Insignia TV. Updating these can help to fix most of these problems.
You must manually update the firmware or software using an older TV model. To do this:
- Go to insigniaproducts.com/products.html, search for your TV model and download the latest updates.
- Download and save them in the root directory of a formatted USB drive.
- Plug the USB drive into your TV, go to Menu> System Info > Update Firmware, and press OK on your remote.
- Your TV will install the updates, after which you should unplug the USB drive and turn it off to complete the update process.
You can automatically update the software and firmware if your Insignia TV is a newer (smart) model. To do this:
- Make sure your TV is connected to the internet.
- Go to Menu > System info (or System) > System updates/Software update
- Check for any available updates for your TV, then select the update option to download and install them.
- Restart your TV to complete the update process.
8. Factory reset your TV
If your TV still has sound issues, reset it to the factory setting defaults. Doing this will delete all the settings on your TV, which can help clear up the issue causing the sound problems.
To factory reset your Insignia TV:
- Go to Menu > System > Advanced System Settings and select “Factory Reset”
- Your TV will then ask you to confirm the decision, after which the reset process will begin.
- With some TVs, you might be asked to enter your admin PIN code/password (the default code is 0000) before the reset can begin.
- After the reset is completed, your TV will reboot, after which you should follow the on-screen instructions to set it up afresh.
If none of these solutions work, you could be dealing with a complex problem, for example, internal hardware failure. In such a case, contact Insignia customer support for additional troubleshooting or take your TV to an authorized service centre for repairs.
