Once you know the cause, you can easily find the appropriate solution.  

Causes of Vizio Analog Audio Out Not Working

If your Vizio TV sound does not work, check the audio cables, ensure the volume is not set to zero or muted, and update the firmware.

See if any of these is the cause of the issue.

Loose Audio Cables

If you have made sure the TV is on, but still no sound is coming out, check for loose audio cables.

Make sure no cables have been knocked or moved. If any has not been seated properly, switch them out.

If you are using an HDMI, change them with your spare. Some manufacturer-provided wires are notoriously flaky.  

Volume is Set to Zero or TV is Muted

Check your audio settings. No sound will come out if your Vizio TV is muted or the volume is set to zero.

This should be a straightforward fix. All you have to do is unmute the TV or turn the volume up.

Vizio TV Firmware

Sometimes, software issues can cause the Vizio audio analog out not working problem. So, always make sure your TV is running the latest firmware version.

In most cases, if your TV is connected to the Internet, it should automatically check for, download, and install updates. But, occasionally, it gets interrupted.

The volume of your Vizio may also fluctuate if the audio settings, such as TruVolume, conflict with your device.

Disable the SRS TruVolume function to fix the issue.

  1. Press the Menu button on your remote control.
  2. Navigate to Audio Settings and go to Advanced Audio.
  3. Turn off the SRS TruVolume.

Other settings that automatically adjust the volume and cause can play a part in the issue: TruSurround, Volume Leveling, and Surround Sound.

Solution #3: Check Audio Cables

If your Vizio TV sound is cutting in and out, you may have a loose or faulty cable.

Make sure all cables are securely connected. Unplug and re-insert all cables from the back of the TV and the source device.

If this doesn’t solve the problem, try the cable on a different TV or use a spare cable on your Vizio TV to determine if the former is faulty.

Also, make sure that the audio cable is compatible with the audio/visual signal. 

Note: While checking cables, make sure they haven’t been cut or become frayed.

Solution #4: Use a Different Audio Output Device

Try a different source device if you are not getting audio from your Cable or Satellite box.

You can also switch inputs to another device, such as a streaming or gaming console.

  1. Connect RCA cables to the audio output of your Vizio TV.
  2. Connect the other ends to the corresponding analog inputs of your powered speakers, soundbar, stereo receiver, or home theater receiver.
  3. Once you plug in everything, turn on the new source device.
  4. Then, follow your TV’s external audio setup instructions.
  5. Select input on your audio system to hear the sound.

Note: If you are using an analog connection, check if the device has any audio enhancement capabilities that may conflict with your Vizio TV.

Solution #5: Update TV Firmware

Another reason your Vizio analog audio out is not working is buggy firmware.

The TV company regularly releases updates to fix common bugs. If you have had your device for a long time, it may be due for an update. 

Typically, your Vizio TV will automatically download and install the new firmware version. However, an unstable connection may interrupt and keep your device from getting updated.

If you suspect that your Vizio TV missed new software, you can manually update it.

  1. Press the V key on your remote control.
  2. Select System on the dropdown menu and click Check Updates.
  3. If an update is available, download and install it.

Note: After installing the updates, restart your Vizio TV. Then, check if the sound issue has been fixed. If not, you may need to perform a factory reset.

Solution #6: Perform a Factory Reset

Restore your TV to its original settings, including the firmware it came with OOTB.

Take note that the reset will delete all of your saved preferences and downloaded content. Do this if you are sure there is no other way to fix the issue.

Here’s how to reset your Vizio TV to factory settings:

  1. With the TV powered on, press the Menu button on the remote.
  2. Click System and find Reset & Admin.
  3. Choose Reset TV to Factory Defaults. When asked for a code, type 0000 as the default code.
  4. Select Reset to confirm.
  5. Wait until the TV has restarted fully before you start the setup process.

Note: If the issue persists after all of the above steps, the TV may have an issue. Check if it’s still under warranty and request warranty service if yes.
