How to connect LG soundbar to Samsung TV
If you want better TV audio, the good news is that an LG soundbar can work well with a Samsung TV.
The best connection method depends on your ports, sound features, and whether you want the simplest setup or the highest audio quality.
This guide explains the main connection options, how to set them up, and how to solve common problems such as no sound, lip sync delay, or remote control issues.
Best ways to connect an LG soundbar to a Samsung TV
There are four common ways to connect these devices: HDMI ARC or eARC, optical cable, Bluetooth, and in some cases Wi-Fi.
Each has tradeoffs in audio quality, convenience, and compatibility.
- HDMI ARC/eARC: Best overall for sound quality and TV remote control integration.
- Optical cable: Reliable and easy, but more limited than HDMI ARC.
- Bluetooth: Fast wireless pairing, but usually lower audio quality and possible delay.
- Wi-Fi or app-based pairing: Available on some LG soundbars, but not the most universal option.
How to connect with HDMI ARC or eARC
HDMI ARC is usually the best answer for how to connect LG soundbar to Samsung TV because it carries audio in both directions and often lets you use one remote for volume control.
If both devices support eARC, you may also get improved support for higher-bitrate formats.
What you need
- An HDMI cable that supports ARC or eARC
- A Samsung TV with an HDMI port labeled ARC or eARC
- An LG soundbar with an HDMI OUT port labeled TV (ARC), ARC, or eARC
Setup steps
- Turn off both the Samsung TV and the LG soundbar.
- Connect the HDMI cable from the TV’s ARC/eARC port to the soundbar’s HDMI OUT (ARC/eARC) port.
- Turn on both devices.
- On the Samsung TV, open Settings and go to Sound.
- Select Sound Output and choose Receiver (HDMI), HDMI ARC, or a similar label.
- Enable Anynet+ (HDMI-CEC) on the Samsung TV if it is not already on.
- On the LG soundbar, select the HDMI input or ARC mode if needed.
Why ARC and eARC are preferred
ARC supports common surround formats and makes setup straightforward. eARC is the newer version and supports more advanced audio formats with better bandwidth, which matters if your TV and soundbar support Dolby Atmos or lossless audio features.
How to connect with an optical cable
If your TV or soundbar does not support ARC, an optical cable is the next best option.
It is stable, simple, and works well for standard TV audio.
Setup steps
- Find the optical output on the Samsung TV and the optical input on the LG soundbar.
- Remove the protective caps from the optical cable ends.
- Connect one end to the TV and the other to the soundbar.
- Change the Samsung TV sound output to Optical or External Speaker.
- Set the soundbar input to Optical using the remote or source button.
Limitations of optical audio
Optical connection does not support HDMI-CEC control, so your TV remote may not always adjust the soundbar volume automatically.
It also does not carry some advanced audio formats supported by HDMI eARC.
How to connect with Bluetooth
Bluetooth is the easiest wireless method and is useful if you want to avoid cables.
It is often fine for casual viewing, but it can introduce audio latency and is less ideal for movies or gaming.
Pairing steps
- Put the LG soundbar into Bluetooth pairing mode.
- On the Samsung TV, open Settings and go to Sound or Connections.
- Select Bluetooth Speaker List or Audio Output.
- Choose the LG soundbar from the list of available devices.
- Confirm the pairing if prompted.
When Bluetooth makes sense
Bluetooth is a practical choice for secondary rooms, temporary setups, or situations where running an HDMI or optical cable is inconvenient.
If you notice a delay between dialogue and video, switch to HDMI ARC or optical.
How to enable the right Samsung TV audio settings
Even a correct cable connection can fail if the TV audio settings are not configured properly.
Samsung TVs often require the output source to be changed manually after you connect the soundbar.
- Sound Output: Set this to HDMI ARC, Optical, Bluetooth Speaker, or Receiver depending on your connection.
- Anynet+: Samsung’s HDMI-CEC feature, needed for many HDMI control functions.
- Digital Output Audio Format: Choose Auto or Pass-Through if available and supported by your equipment.
- TV Speaker: Disable this when using an external soundbar to avoid mixed audio.
How to set up the LG soundbar correctly
LG soundbars often switch automatically, but some models require manual input selection.
If the soundbar does not play audio, check the input source on the unit or in the remote menu.
- Select ARC or HDMI for HDMI connections.
- Select OPT or Optical for optical cable connections.
- Use the Bluetooth input for wireless pairing.
- Increase volume on the soundbar itself before troubleshooting the TV.
Common problems and fixes
Many setup problems come from input mismatch, disabled CEC settings, or incorrect cable placement.
These issues are usually easy to fix once you know what to check.
No sound from the LG soundbar
- Confirm the cable is connected to the TV’s ARC/eARC or optical output, not a regular input.
- Make sure the Samsung TV sound output is set to the soundbar.
- Check the LG soundbar input source.
- Power cycle both devices by unplugging them for about 30 seconds.
TV remote does not control the soundbar
- Turn on Anynet+ on the Samsung TV.
- Use HDMI ARC instead of optical or Bluetooth if you want remote integration.
- Reboot both devices after enabling HDMI-CEC.
Audio delay or lip sync problems
- Use HDMI ARC or eARC for the most stable sync.
- Check the Samsung TV audio delay setting if available.
- Reduce Bluetooth use for video content if delay is noticeable.
Soundbar connected but audio is weak or distorted
- Try a different HDMI or optical cable.
- Set the TV digital audio output to Auto or PCM if the current mode causes issues.
- Disable extra audio processing features temporarily to test clean playback.
Which connection method is best for your setup?
The best choice depends on your equipment and priorities.
For most users, HDMI ARC or eARC is the recommended method because it balances audio quality, convenience, and control.
- Choose HDMI ARC/eARC if both devices support it and you want the cleanest setup.
- Choose optical if HDMI ARC is unavailable or unreliable.
- Choose Bluetooth if you want quick wireless audio and can accept some compromise in quality.
Helpful compatibility checks before you start
Before buying cables or changing settings, verify the ports on both devices.
Samsung TV models vary, and LG soundbars differ by generation, so the labels on the back panels matter more than the brand names alone.
- Look for HDMI ARC or eARC on the Samsung TV.
- Check whether the LG soundbar has an HDMI OUT port for TV connection.
- Confirm whether your soundbar supports Dolby Atmos, DTS, or other formats you want to use.
- Match the cable type to the port type instead of relying on adapters unless necessary.
Once the connection method is chosen, the setup usually takes only a few minutes.
The key is matching the correct ports, selecting the right TV output, and enabling the control features that let the two brands work together smoothly.
