Speakers & soundbars

Soundbar volume won't go up or down

This usually means the soundbar is receiving volume commands from the wrong source (like the TV remote instead of its own), or CEC volume control is misconfigured. Checking which remote controls volume fixes most cases.

Symptoms

  • TV remote volume buttons don't affect soundbar sound
  • Soundbar's own remote adjusts volume but TV remote doesn't
  • Volume display shows a fixed level regardless of button presses
  • Volume changes are extremely small or delayed

Likely causes

  • CommonHDMI-CEC volume control not enabled between TV and soundbarCEC needs to be enabled on the TV for its remote to control soundbar volume over HDMI-ARC.
  • CommonTV remote sending volume commands to the TV's internal speakers instead of the soundbarIf TV speakers aren't disabled, volume changes may not route to the soundbar.
  • PossibleSoundbar remote batteries lowA weak signal from the dedicated remote can cause intermittent or failed volume changes.
  • PossibleSoundbar's volume locked or in a fixed-output modeSome soundbars have a fixed-volume/passthrough mode meant for external control.
  • Less commonInternal fault in the soundbar's volume control circuitA stuck volume control can leave the unit at one level despite valid commands.

What to do

  1. Enable HDMI-CEC (may be labeled Anynet+, Bravia Sync, SimpLink, etc.) in the TV's settings so the TV remote can control soundbar volume.
  2. Confirm the TV's internal speakers are set to off or the audio output is set to the soundbar/ARC.
  3. Try adjusting volume using the soundbar's own dedicated remote to isolate whether it's a CEC issue or a soundbar fault.
  4. Replace the batteries in the soundbar's remote.
  5. Check the soundbar's settings menu for any fixed-volume or line-out mode and disable it if enabled.
  6. Power cycle the TV and soundbar by unplugging both for a minute.

Tools and parts

  • Fresh batteries

When to call a pro

If the soundbar's own remote also fails to adjust volume, the internal volume control circuit likely needs professional repair.
