How to connect Samsung soundbar to LG TV
If you are trying to figure out how to connect Samsung soundbar to LG TV, the good news is that the process is usually straightforward once you choose the right connection method.
The best option depends on your TV model, your soundbar ports, and whether you want the highest audio quality or the simplest setup.
Samsung soundbars and LG TVs are compatible through HDMI ARC, HDMI eARC, optical audio, and Bluetooth, but each method has different benefits, limitations, and setup steps.
What you need before you start
Before connecting the devices, check the ports on both the LG TV and the Samsung soundbar.
Most modern LG OLED, QNED, NanoCell, and LED TVs include HDMI ARC or eARC, while many Samsung soundbars include HDMI ARC, optical input, and Bluetooth.
- An HDMI cable rated for ARC or eARC
- An optical digital audio cable if using Toslink
- Your TV remote and soundbar remote
- Access to the LG TV settings menu
- Access to the Samsung soundbar source or input button
It also helps to confirm the exact model numbers.
Some older LG televisions and entry-level Samsung soundbars support only basic ARC or optical audio, while newer devices may support Dolby Digital, Dolby Atmos, and CEC control.
Best method: HDMI ARC or eARC
HDMI ARC is usually the best balance of quality and convenience.
HDMI eARC is even better if both devices support it, because it can carry higher-bandwidth audio formats such as Dolby Atmos with less compression.
Why HDMI ARC and eARC are preferred
- Single-cable audio connection from TV to soundbar
- Better sound quality than standard Bluetooth
- TV remote can often control soundbar volume through HDMI-CEC
- Supports advanced formats on compatible models
How to connect using HDMI ARC or eARC
- Find the HDMI port labeled ARC or eARC on the LG TV.
- Connect one end of the HDMI cable to that port.
- Connect the other end to the HDMI OUT or TV ARC port on the Samsung soundbar.
- Turn on both devices.
- On the LG TV, open Settings, then Sound, and select Sound Out.
- Choose HDMI ARC, HDMI eARC, or External Speaker depending on your menu labels.
- On the Samsung soundbar, select the correct input if it does not switch automatically.
If the TV does not detect the soundbar, go into the LG Sound settings and make sure SIMPLINK, which is LG’s HDMI-CEC feature, is enabled.
This allows the TV and soundbar to communicate properly.
How to connect Samsung soundbar to LG TV with optical cable
If HDMI ARC is unavailable or unreliable, optical audio is the most common alternative.
It delivers clean digital audio and works on many older TVs, though it does not support the same level of control integration as HDMI ARC.
Optical connection steps
- Locate the optical digital audio output on the LG TV.
- Remove the protective caps from both ends of the optical cable if present.
- Insert one end into the TV’s optical output.
- Insert the other end into the Samsung soundbar’s optical input.
- Turn on both devices.
- On the LG TV, go to Sound Out and select Optical Out or External Speaker.
- On the soundbar, switch the input to D.IN or Optical using the remote or source button.
Optical audio supports stereo and many surround formats like Dolby Digital, but it does not carry advanced audio formats as well as eARC.
It also usually requires separate volume control, since TV remote integration may be limited.
How to connect wirelessly with Bluetooth
Bluetooth is convenient when you want a cable-free setup, but it is generally not the best choice for movies or gaming because it can introduce latency.
It works well for casual viewing and music playback.
Bluetooth pairing process
- Put the Samsung soundbar into Bluetooth pairing mode.
- On the LG TV, open Settings, then Sound, then Sound Out.
- Select Bluetooth and wait for the TV to scan for nearby devices.
- Choose the Samsung soundbar from the list.
- Confirm the pairing if prompted.
Some LG TVs show Bluetooth devices under a dedicated Sound Sync or Bluetooth Speaker list.
If the soundbar does not appear, move it closer to the TV, reset pairing on the soundbar, and try again.
Which connection should you choose?
The best option depends on your priority:
- HDMI eARC: best for audio quality and Dolby Atmos support
- HDMI ARC: strong all-around option for most users
- Optical: good fallback for older equipment or HDMI problems
- Bluetooth: easiest wireless setup, but lower performance for video
If your LG TV and Samsung soundbar both support eARC, use that first.
If not, ARC is usually the next best choice.
Optical is ideal when ARC fails, and Bluetooth works best for simple, low-setup use cases.
LG TV settings that affect soundbar performance
Even when the cable is correct, the wrong TV settings can prevent sound from playing through the soundbar.
LG televisions often require a few audio and HDMI control options to be enabled.
Important LG settings to check
- Sound Out: set to HDMI ARC, Optical, or Bluetooth depending on the connection
- SIMPLINK: enable for HDMI ARC and CEC control
- Digital Sound Output: set to Pass Through or Auto when available
- eARC Support: enable if both devices support eARC
If you are using a streaming app such as Netflix, Disney+, or Apple TV, confirm that the app audio output is set correctly and that the TV is not muted.
Some apps may default to stereo if the content or settings are limited.
Samsung soundbar settings that may help
Samsung soundbars often auto-detect the input, but manual selection can fix issues quickly.
Use the source button or the soundbar remote to switch between HDMI, D.IN, and Bluetooth modes.
If the audio sounds delayed or the wrong input is active, power-cycle the soundbar and reconnect the cable.
On some Samsung models, firmware updates improve HDMI handshake performance and codec support.
If you are having repeated issues, check the Samsung support site or SmartThings app for updates.
Troubleshooting common problems
No sound from the soundbar?
- Make sure the TV Sound Out setting matches the connection type
- Verify the HDMI cable is connected to the ARC or eARC-labeled ports
- Test a different HDMI or optical cable
- Power off both devices, unplug them for 30 seconds, and reconnect
Volume control does not work?
- Enable SIMPLINK on the LG TV
- Make sure the soundbar is connected through HDMI ARC or eARC, not just HDMI input
- Check whether the TV remote is set to control external audio devices
Audio is delayed or out of sync?
- Use HDMI eARC if available
- Disable Bluetooth for video content
- Adjust LG AV Sync settings if your model includes them
- Try a high-quality HDMI cable certified for ARC or eARC
Soundbar keeps disconnecting?
- Re-pair Bluetooth devices if using wireless mode
- Update firmware on both devices
- Confirm the soundbar is not switching sources automatically
- Move interfering wireless devices farther away
Tips for getting the best audio quality
For home theater use, a direct wired connection is usually best.
If your Samsung soundbar supports Dolby Atmos, a TV with eARC can preserve more of that audio detail.
For gaming, HDMI ARC or eARC is also preferable because it is more stable than Bluetooth and reduces latency.
Use the shortest reliable cable length possible, but do not sacrifice quality for convenience.
Certified HDMI cables matter more on eARC setups, especially when passing advanced formats between devices.
When to use a soundbar reset
If the LG TV and Samsung soundbar still will not connect, a reset can clear pairing and handshake problems.
Restart both devices first.
If that fails, reset the soundbar according to Samsung’s model-specific instructions and reconfigure the TV audio output from scratch.
In stubborn cases, unplug both devices from power, disconnect all audio cables, reconnect them carefully, and then reselect the output source in the LG settings menu.
This often resolves detection problems after firmware changes or accidental input switching.
