Samsung TV Soundbar Not Working: How To Fix It (2026)

Your Samsung TV is cutting out on the soundbar, playing sound only from the TV speakers, or sending nothing to external speakers at all.

This is a common HDMI ARC and eARC problem, and it can usually be fixed with a few setting changes and one cable check.

Work through the fixes in order; the first four take about ten minutes and cover most cases.

Why is my Samsung TV not sending sound to the soundbar?

What you hear	Likely cause	Start with
No sound from the soundbar at all	Wrong output, port or soundbar source	Fixes 2, 3 and 4
Sound only from TV speakers	Sound Output not set to the soundbar	Fix 3
Audio cuts out for a second or two	HDMI eARC or audio format handshake	Fix 5
Soundbar works but TV remote cannot change volume	Anynet+ (HDMI-CEC) off	Fix 4
Q-Symphony option missing or silent	Model, connection or Wi-Fi requirement	Fix 6
Voices out of sync with lips	Audio delay	Fix 8

Menu names vary by model, region and software version, so yours may differ slightly from the paths below.

Fix 1: Power-cycle the TV and the soundbar

Restarting both devices forces them to renegotiate the HDMI connection.

1. Turn off the TV and the soundbar and unplug both from the wall.
2. Wait a few minutes, then plug the TV in and let it reach the home screen.
3. Plug in and turn on the soundbar, then wait about 30 seconds before playing anything.

Powering the TV first is a community-recommended order rather than an official Samsung step.

Fix 2: Use the right HDMI port and cable

Samsung says to connect the TV’s port labeled ARC to the soundbar’s HDMI OUT port.

• Port: Use the TV HDMI port marked ARC or eARC, not a regular HDMI input.
• Cable: For eARC, Samsung Canada says to use an eARC-capable cable such as an HEAC or HEC cable.
• Isolate the problem: Disconnect all other HDMI devices and test with only the TV and soundbar on.

Reseat both ends, and swap in a different cable if the soundbar still stays silent.

Fix 3: Set Sound Output to the soundbar

If you hear the TV speakers but not the soundbar, the TV is still sending sound to itself.

1. Press Home and go to Settings > All Settings > Sound > Sound Output.
2. Choose Soundbar (HDMI) or your device.
3. Play audio and check the soundbar volume.

Fix 4: Turn on Anynet+ and set the soundbar source

Samsung’s HDMI troubleshooting steps include making sure Anynet+ (HDMI-CEC) is on.

1. Open Settings > All Settings > Connection > External Device Manager (some Samsung pages list it under General).
2. Turn on Anynet+ (HDMI-CEC).
3. On the soundbar remote, press Source and select D.IN; on 2024 and later soundbars, choose ARC or eARC.

The soundbar may switch to TV ARC on its own after a few seconds.

Fix 5: Check HDMI-eARC Mode and the audio format

Open Settings > All Settings > Sound > Expert Settings to reach both settings.

Setting	Samsung recommends	Community workaround for dropouts
HDMI-eARC Mode	Auto	Off, which forces standard ARC
Digital Output Audio Format	Auto	Other formats, tested one at a time
Anynet+ (HDMI-CEC)	On	Off, which loses TV-remote soundbar volume control

Start with Samsung’s Auto settings, and only try the workaround column if the dropouts continue.

Standard ARC cannot carry the lossless audio formats that eARC can, so Off trades format support for stability.

Samsung says Digital Output Audio Format should be left unchanged if you are not using external speakers, soundbars or headphones.

Fix 6: Check Q-Symphony requirements

Q-Symphony plays sound through the TV speakers and a compatible Samsung audio device together.

Requirement	Samsung’s details
TV	DU7000 and above, and LS03D (2024 setup page)
Audio device	A Samsung soundbar that supports Q-Symphony, or a Music Frame
Wired connection	Soundbar source on D.IN, or ARC/eARC on 2024 and newer soundbars
Wi-Fi connection	Same network as the TV; screen mirroring can disconnect it

1. Go to Settings > All Settings > Sound > Q-Symphony Setup.
2. Choose your soundbar or Music Frame and select Apply.
3. To turn it off, open Sound Output and select TV Speaker.

Fix 7: Update the TV, then check the soundbar firmware

Both Samsung and its eARC troubleshooting page recommend updating the TV software if the problem continues.

1. Go to Settings > All Settings > Support > Software Update.
2. Select Update Now and let the TV restart.
3. Check your soundbar model’s Samsung support page for firmware.

Samsung notes that video and audio settings may reset to defaults after an update, so re-check Fixes 3 to 5.

Fix 8: Correct audio that is out of sync

If sound plays but does not match the picture, adjust the delay rather than the connection.

1. Open Settings > All Settings > Sound > Expert Settings.
2. Select Digital Output Audio Delay.
3. If audio runs ahead of the picture, move the slider to the right.

This option only appears when the soundbar or speakers connect through HDMI-eARC or SPDIF, and Samsung says no setting fixes Bluetooth or wireless speaker delays.

Fix 9: Reset sound settings or switch to optical

If settings were changed over time, reset them first.

• Reset: Go to Sound > Expert Settings > Reset Sound.
• Optical: Run an optical cable from the TV to the soundbar and set the soundbar source to D.IN.

Optical avoids the HDMI ARC handshake, but it cannot carry the lossless audio formats that eARC supports.

When should you contact Samsung support?

If the soundbar still has no sound after another device and cable test, Samsung says to request service.

• Phone: 1-800-SAMSUNG (1-800-726-7864), weekdays 8 AM to 9 PM Eastern and weekends 8 AM to 6 PM Eastern.
• Have ready: TV and soundbar model numbers, plus the steps you already tried.
• Quick test: Try the soundbar on a different ARC-capable TV to see which device is at fault.
