Vizio televisions have advanced sound settings that are often tricky to troubleshoot. Fortunately, when the Vizio TV volume keeps going up or you experience a no sound problem, there is a simple solution available. In many cases, it's a simple conflict between programs controlling the sound settings and a brief navigation to and adjustment of these settings will resolve the problem.

Vizio No Sound

A no sound problem is less common than sound fluctuation issues but it does happen on occasion. Ideally, the solution is simple and does not require any physical changes or repairs to the hardware. Start with the easy stuff and make sure the television is not muted. Next, turn up the speaker volume and check for sound. Turn the station to ensure the issue is local to the television.

Next, inspect the speaker system. Integrated speakers are often used but a soundbar or exterior sound system can fail due to a lack of power. Make sure the speaker system is turned on and is connected to the television. Physically inspect power cords and speaker wires for loose or bad connections. Navigate with the remote Audio then to Audio Settings to ensure the speakers are turned on within the television settings as well.

The other common no sound issue involves a conflict with the cable or satellite box. The box can override the sound settings and you must turn up the sound through the box rather than the television. Select the Cable option on your remote and turn up the sound to test for this issue. You can change the primary sound control option in the Audio Settings and Speaker Settings portion of the control panel.

Volume Fluctuation Issues

When the Vizio TV volume goes all the way up or fluctuates randomly, a conflict of devices is present. The Vizio soundbar volume fluctuates in a similar manner as the television stock speakers and the resolution process is the same for both speaker options. Ultimately, the way to fix the sound fluctuations is through simple settings changes to prevent program conflicts.

When the volume fluctuates, access the Audio Settings using the remote control. The SRS TruVolume is the most prevalent conflict that causes sound fluctuations. Use the remote to select Main Menu then Audio Settings followed by Advanced Audio. Lastly, turn off the SRS TruVolume to remove the conflict and stop the volume fluctuations.

Now test the volume to see if the new settings function properly. If the volume continues to fluctuate, the TruVolume settings are not the primary issue. In this instance, check the cable or satellite box settings for conflicts. Turn off the box volume to only use the soundbar or speaker system.

If the problem persists, check the settings on all apps and turn off the volume controls within apps so the only controls being used are those determined by your primary preferences.

Seeking Outside Support

In rare cases, the volume controls are very difficult to assess and troubleshoot. Utilize the Vizio customer support forums and channels to seek specialized assistance. The Vizio community is capable of helping with difficult problems unique to your situation.

If the volume is intermittent or no volume exists, the potential for a hardware malfunction exists. In this instance, check the Vizio warranty for repair or replacement potential. Your point of purchase may also have offered an extended warranty service that may cover hardware failures. If the warranty does not cover the television, seek professional repair services for a quote on new speakers or a repair to the existing system.
