It is always good to have a troubleshooting checklist before any issue is escalated.
I personally have faced several volume-related issues on my Vizio TV. Keeping this in mind, I have made a checklist for resolving the issue.
A few weeks ago, I wanted to watch a very important football match. I had been waiting the entire day to watch it after work.
But as soon as I turned my Vizio TV on, I was terribly annoyed to find that there was no audio on my TV.
From my past experiences, I have realized that having an audio-related issue does not necessarily mean that there is some technical issue with the TV.
There can be very obvious causes, like your TV being on mute. Sometimes, the audio output device is connected to the 3.5 mm jack without you knowing.
To create this checklist, I thoroughly went through the audio options on my Vizio TV and watched some very useful youtube videos to understand the basics of audio transmission on Vizio TVs.
I also went through the FAQs available online to understand the audio issues that are most frequently faced by Vizio TV users. I am sure that this checklist would be helpful for you as well.
To fix the volume on your Vizio TV, make sure your TV is not on mute, check if the remote control is working properly, check the HDMI cable, and make sure that the satellite box is not on mute.
This troubleshooting checklist below will solve audio issues on your Vizio TV in most cases.
Check if your Remote Control Works

Sometimes, due to dead batteries or other issues, Vizio TV remotes stop working properly.
That may very well be the case with you if you are facing issues with your TV volume.
It is therefore always a good idea to start troubleshooting by checking if your remote is working properly.
Turn on your TV and press the volume functions on your remote. If the TV is not responding to the remote control then try replacing the battery in the remote.
If changing batteries does not work then unfortunately it is time to get a new remote.
Move to the next step if you find that the remote control is working properly.
Ensure your Vizio TV is not Muted

You may absent-mindedly have put your Vizio TV on mute. If that is the case, you will not hear any audio from the TV if that is the case.
Try unmuting your Vizio TV by pressing the mute button on the Vizio remote.
Checking the Vizio TV Volume may help if your TV is not on mute.
Check your Vizio TV Volume
So you have pressed the mute button but you still cannot hear anything. It may be the case that your TV volume has been set to zero.
Use your TV remote and press the ‘+’ side of the volume button.
Make sure that the TV volume is adjusted to an audible level above zero.
If the TV volume is adjusted properly but you still cannot hear anything then checking your HDMI cable may help.
Check your HDMI Cable

HDMI cables play a very important role in transmitting audio and video signals to the TV.
Your Vizio TV may face volume issues if the HDMI cable that connects your TV to an external device is faulty.
If you can see video on your TV but there is no audio then it is very much possible that your HDMI cable is broken.
You can try using a different HDMI cable to check if the audio issue gets sorted.
If the audio issues get sorted upon using another cable, this means that the previous HDMI cable you were using was faulty.
Check the Volume Settings on your Set-Top Box
Audio and video signals are transmitted to the TV through the set-top box if you are using a set-top box.
Therefore, it is important to check the volume setting on your set-top box if you are facing audio issues.
Use the remote to first make sure that the set-top box is not on mute. After that, use the remote to increase the volume to audible levels above zero.
If this does not work then move to the next step.
Check if SAP has been Enabled on your Vizio TV

SAP, short for Secondary Audio Programming, is used to listen to the video on the TV in a language other than the original language.
It is usually a second audio stream that is included in the TV show.
SAP can be turned off on your TV if you wish to watch the show in the original language. ‘SAP’, ‘Audio Select’, ‘B-Audio’, ‘MTS’ etc are all popular menu labels for SAP.
Follow these steps to ensure that SAP is enabled on your Vizio TV:
- Press the ‘menu’ button on your TV remote.
- Select the ‘Audio’ option from the list of available options.
- Select the ‘SAP’ Option.
- Select the desired setting.
Turning off DTS TruSurround on your Vizio TV may also help if issues persist.
Turn Off DTS TruSurround on your Vizio TV
A lot of Vizio TV users face volume issues because of the TV’s advanced audio settings.
A conflict between the program you are watching and DTS TruSurround may be causing audio issues with your Vizio TV.
Turning off the advanced setting may help in such a situation. To turn off DTS TruSurround on your Vizio TV, follow these steps:
- Go to Main Menu.
- Go to Audio Settings.
- Go to Advanced Audio.
- Turn off DTS TruSurround.
If this does not work, move to the next step.
Check if a 3.5mm Audio Cable has been Plugged in

Your Vizio TV speakers will not transmit any audio if any device has been left plugged into the audio jack of the TV.
It is possible that a device such as an earphone or a headphone has been left plugged in from before.
The TV would send audio output to the connected device if this is the case.
Audio output on these devices would obviously not be audible if you are not wearing them.
Disconnect the device and then try increasing the volume on the TV.
Resetting your Vizio TV might help if no device is connected to the audio port.
Reset your Vizio TV
If none of the above ways have worked to resolve your audio issues then resetting your Vizio TV would most likely set it right.
- Press the ‘menu’ button on your Vizio remote.
- Navigate to and select the ‘System’ option, using your remote.
- Navigate to and select the ‘Reset & Admin’ option.
- Select ‘OK’
- Put the parental code, if you have manually put one.
- If you have not manually put any parental code then put ‘0000’ as the password when asked for.
- Select the ‘Reset’ option.
- Press ‘OK’
- Wait till the TV turns off.
After a while, the TV will turn on again and the Setup App process would begin.
Contact Support

It may be possible that none of the above work and you are still facing audio issues.
In such a case, you must escalate the issue and seek help from the Vizio customer support team.
You can find the relevant customer care information on the Vizio Support website.
Conclusion
You would know by now that there can be numerous reasons why you are facing audio issues on your Vizio TV.
