Samsung TVs are a popular choice amongst smart TV enthusiasts these days. They guarantee utmost build quality, unimpeachable reliability, and seamless performance for years on end. However, they are still a piece of technology and can go wrong. Is your Samsung TV getting louder by itself? If so, what can you do to quell the problem? Is it a sign of something trivial, or is it an issue?

Most Samsung QLED TVs get louder due to the Sound Sensor designed to detect surrounding sounds and adjust the TV volume accordingly. If this feature is on, the user may observe rises and drops in volume happening automatically on occasion.

If your Samsung TV is old or not a Q series model, the problem could be due to incorrect settings or damaged hardware. Read on to learn more tips on troubleshooting this problem on your TV.

Why Does My TV Volume Go Up By Itself?

In general, many reasons can be behind a TV’s volume issue. These include faulty remote control, TV software bugs, wrong audio settings, and hardware problems. Some TVs also have automatic volume adjustment features that may be responsible for this problem.

When this problem occurs, the first thing you should do is remove the remote’s batteries and wait for some time to see if the problem goes away. If it does, you should replace the remote control or get it repaired.

Update Software

If your TV’s software is not up-to-date, it can result in strange problems called software bugs. So download any software updates as soon as they become available. 

If you have a Samsung TV and Auto Update is disabled, follow these steps to get updates:

  • Open Settings by using the remote.
  • Select Support.
  • Select Software Update.
  • Select Update Now.

For auto-update, you need to keep your TV connected to the internet. Updates will be downloaded (when available) in the background. The TV will install these updates when you turn it ON the next time. Check this information about Samsung TV software updates before starting the process. Remember, regular updates keep the software bugs away! If updating the software did not help, you should contact customer support. 

Check Audio Preferences

Sometimes, the wrong audio preferences on a TV can result in abrupt changes in the volume without you doing anything. For example, the HDMI Audio Input Format setting on some TVs can be incorrect. Samsung TV users are to change this setting by taking these steps:

  • Select Settings and navigate to Sound.
  • Choose Expert Settings.
  • Select HDMI Audio Input Format.
  • Change from Bitstream to PCM.

The problem can arise when the output audio is Surround Sound instead of Stereo on some other TVs. Also, older TVs may occasionally develop this issue because of a struck onboard volume switch, which you can replace by opening the back panel of the TV or getting a technician to do it.

Ensure that the automatic volume control feature on your TV is disabled. The sound sensor on Samsung QLED TVs can be turned on or off by sliding the button in the slot near the power button to the left or right, respectively. A pop-up confirmation message will appear on the screen when the sensor position is changed. If the problem persists, you should contact Samsung support before trying any fixes. 

Why Is the Sound On My Samsung TV So Bad?

A Samsung TV may output distorted audio due to a loose HDMI ARC or audio cable connection, faulty cables, or a damaged source device. If the sound distortion is not frequent and happens only on one or two particular video /audio clips, the problem is not with the TV but with those files.

Here are some tips that will help you avoid bad sound quality on your Samsung TV:

  • Check all the connections between your TV and the external devices to ensure that none of them are loose.
  • If there are glitches in the video during audio distortion, the HDMI port may be defective. In this case, you may require assistance from Samsung.
  • Buy a new HDMI cable if the existing one is not working.
  • Use the same cables from the same ports but with a different external source to determine if the source is faulty.
  • Adjust all equalizer settings in the center to see if the problem goes away.
  • If not inconvenient, you can also perform a factory reset on your TV. Sometimes a simple reset is enough to solve such problems.

To do a factory reset on your Samsung TV is simple. Here’s a quick video:
