Samsung Tv Volume Keep Going Down

Has your Samsung TV volume started decreasing on its own lately? You’re not alone. Many Samsung smart TV owners face this frustrating issue with no clear solution in sight.

Don’t worry – in this comprehensive guide, we’ll explore the top 7 reasons why your Samsung TV volume goes down randomly and how to fix them for good.

What Causes Samsung TV Volume to Decrease Randomly?

There are several factors, both software and hardware related, that can trigger your Samsung TV’s volume to fluctuate, dip, or even get stuck at low levels unexpectedly.

Software Issues

Outdated firmware, corrupted system files, HDMI handshake problems, and buggy apps can all send incorrect signals to your TV’s audio processors – disrupting normal volume output. Smart features that attempt to optimize sound can sometimes go haywire.

Hardware Problems

Physical damage to internal volume control circuits, remote control faults, stuck buttons, faulty connections with external audio gear, and sensor issues can manifest as random volume drops.

Thankfully, most volume problems are easy to troubleshoot and resolve at home without an expert.

Green screen problems on Samsung TVs can have different causes – this troubleshooting article explores the most likely issues.

1. Reset Your Samsung TV Audio Settings

Resetting your audio settings restores any misconfigured parameters that may be lowering volume back to factory defaults.

Here’s how to reset audio on Samsung TVs:

  1. Press Home button on remote and select Settings.
  2. Open Sound menu > Expert Settings.
  3. Choose Reset Sound option and confirm.

This will clear any problematic customized settings causing erratic volume behavior. Recheck if volume drops still occur before moving to next steps below.

2. Turn Off Automatic Volume Limiter (AVL)

Samsung TVs have an Automatic Volume Limiter (AVL) feature enabled by default to prevent hearing damage from sudden loud sounds.

  • It detects volume spikes in content or ads and restricts max volume.
  • Great safety feature but can cause random volume drops if overly sensitive.

To disable AVL on your Samsung TV:

  1. Go to Menu > Sound > Speaker Settings
  2. Locate the AVL setting and turn it Off.

With AVL disabled, your TV’s peak volume capabilities are restored so drops should no longer occur.

3. Disable Sound Sensor and Voice Amplifier

Samsung’s Adaptive Sound and Active Voice Amplifier features use built-in mics and sensors to optimize audio based on your viewing environment and content.

While helpful, bugs can cause these smart audio aids to instead lower volume, mute sound, or create echo/static unexpectedly.

To turn them off:

  1. Open Settings > Intelligent Mode Settings
  2. Disable Active Voice Amplifier and/or Sound Sensor

With these sensor reliant features switched off, any associated volume dipping issues should stop. Do test volume before and after to confirm.

4. Check Board Volume Control and Connections

The internal board volume control regulates your Samsung TV’s sound signal levels before output. If damaged or corroded, it can directly cause volume to decrease, become static or cut out entirely.

Same goes for any loose/faulty audio connections from board to speakers, WiFi module etc.

Here’s how to inspect and fix:

  1. Unplug TV safely and remove back cover.
  2. Examine board volume control unit and surrounding connections for damage.
  3. Clean oxidation, replace frayed wires, mend solder joints as needed.
  4. Test buttons/sensors and ensure no stuck pieces impeding movement.

While complex, fixing board and audio link issues directly resolves hardware-based causes of Samsung TV volume drops. Seek assistance if needed.

5. Update Bitstream Audio Settings

Bitstream refers to digital audio signal processing from source to TV output. Errors here manifest as volume fluctuation, distortion, lag, and cut outs.

Optimizing bitstream settings fixes this:

  1. Open Audio Format menu & disable Dolby/DTS compatibility
  2. Enable PCM under HDMI Input Audio Format
  3. Choose Raw/Unprocessed audio data streams

Adjusting bitrate, codec, and data processing modes prevents audio corruption – restoring consistent volume control.

6. Fix Remote Control and Button Issues

Sticky buttons on either your Samsung TV remote or side panel can inadvertently trigger volume to decrease.

Here’s how to diagnose and fix button issues:

  • Inspect remote closely and press every key several times to release dirt/debris
  • Check side volume, channel, power keys on TV housing – clean any stuck ones
  • Replace remote batteries first if unresponsive/laggy
  • Try manual buttons if remote still misbehaves
  • Finally, order replacement remote if needed

With clean, responsive external controls – accidental volume dips will cease. Please proper remote handling to avoid future button issues.

7. Disconnect External Audio Devices

Soundbars, Bluetooth speakers, AV receivers connected to your Samsung TV can potentially interfere with internal volume regulation – triggering unprompted drops, fluctuations etc.

How to rule out interference:

  • Switch off/disconnect ALL external sound devices including game consoles & streaming boxes.
  • Directly test TV’s internal speakers alone for volume stability.
  • If volume control returns to normal, an external device was the culprit.
  • Reconnect one device at a time with updated settings to isolate root cause.

Carefully testing solo TV performance helps pinpoint whether connected audio gear is clashing with TV volume boards. Choose optical/analog connections if possible.

8. Update TV Software and Firmware

Outdated firmware is a leading cause of Samsung TV glitches including the volume decreasing randomly.

Here’s how to update:

  1. Go to Settings > Support > Software Update
  2. IF available, install latest firmware OTA
  3. Alternatively download firmware on USB from Samsung’s support site
  4. Carefully follow prompts to install from USB
Software Update Samsung Tv

Staying updated with Samsung’s continuous firmware releases prevents software-related audio issues down the road.

Find out why some Samsung TV models turn themselves on automatically with this explainer on Samsung TV turning on randomly.


Q1: Why does my Samsung TV suddenly go quiet?

This usually happens when automatic volume limiter (AVL), sound sensors or active voice amplifier features kick in incorrectly, drastically lowering the volume. Turn them off using the methods described above.

Q2: How do I stop my Samsung TV volume going up and down?

Frequent Samsung TV volume fluctuation has various causes like sound sensor bugs, HDMI conflicts with audio devices, IR remote glitches or faulty internal volume control hardware. Follow the troubleshooting guide to isolate and fix the specific problem based on your observations.

Q3: Why is my Samsung TV stuck at low volume?

If your Samsung TV volume is stuck at low levels around 10 to 20 range inexplicably, it likely indicates hardware damage – either remote button or internal board volume control issues. Inspect both and replace parts accordingly.

Random and erratic TV volume drops can certainly be frustrating to deal with. Hopefully, this comprehensive troubleshooting guide has helped you better understand the diverse reasons behind Samsung TVs volume going down spontaneously and actionable solutions to restore normal functionality for good.

Do remember that both software and hardware faults can trigger this problem so methodically checking and correcting both is key.
