Modern home entertainment systems require high-quality sound, which built-in TV speakers often fail to deliver. LG owners have the unique opportunity to integrate their devices into a single ecosystem using wireless communication protocols. Connecting external speakers, such as the popular LG series, XBoom Go, allows you to significantly expand the sound stage and add depth to the low frequencies without unnecessary wires.
The synchronization process can be accomplished in a variety of ways, but Wi-Fi and LG's proprietary technologies provide the most stable high-resolution audio stream. Unlike a standard Bluetooth connection, wireless connection via a local network or proprietary utilities minimizes latency and allows volume control using the TV remote. This transforms a regular movie night into a full-fledged cinematic experience.
In this article, we will examine in detail all the available methods for integrating a speaker with a TV, paying special attention to the nuances of working in the environment WebOSYou'll learn how to properly prepare equipment, configure a network, and resolve common issues users encounter during initial setup.
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure your devices are technically ready to communicate. Not all LG TV models support direct wireless connection to third-party Bluetooth speakers via the sound menu, although most modern Bluetooth-based systems WebOS 4.0 and above have this function. Columns of the series XBoom Go (models PL, PK, XK) are equipped with Bluetooth and Wi-Fi modules, but their operation in conjunction with TV requires certain conditions.
It is critical that both devices are on the same local network if you plan to use smart home features or the app. LG ThinQ. The router must support the standards. 802.11n or 802.11ac to ensure sufficient channel bandwidth. Older routers can create latency, leading to audio and video desynchronization.
- 🔌 Make sure the speaker is charged or connected to a power source via the original adapter.
- 📡 Check that the TV and smartphone (for setup) are connected to the same Wi-Fi network.
- 🔄 Update your TV firmware to the latest available version via the settings menu.
- 🔊 Make sure that the speaker is not in pairing mode with another device.
⚠️ Attention: The "Sound Sync" feature works differently depending on the version of the webOS operating system. In older versions, the menu may be called "LG Sound Sync," while in newer versions, it may simply be called "Sound Manager" or "Output Device Selector."
It's also worth considering that some budget TV models may not have a built-in Bluetooth module, which is necessary for the primary handshake protocol, even if they advertise Wi-Fi support. In such cases, using an external Bluetooth adapter or an optical cable will be the only option, but we'll focus on wireless methods.
Sound Sync Method: Classic Bluetooth Connection
The most common method, which is often confused with Wi-Fi due to its wireless nature, is the technology LG Sound Sync. Essentially, the TV uses its Bluetooth module to search for and pair with speakers. This method doesn't require complex network setup but provides sufficiently high signal quality for most use cases.
To initiate standby mode, press and hold the power button or the dedicated Bluetooth button on the speaker until the indicator light appears. On an LG TV, go to the sound settings, where the system will automatically search for available devices within range.
The search process may take 10 to 30 seconds. If your model name appears in the list of detected devices, for example, XBoom Go PL7, you must select it to complete the pairing. Once successfully connected, the TV will automatically switch audio output to the external speakers.
- 📺 Press the settings button (gear) on the TV remote control.
- 🔊 Go to the section
All settings → Sound → Select audio output device. - 🔍 Select an item
LG Sound Sync (Bluetooth)and start the search. - ✅ Click on the name of your speaker in the list of found devices.
Walls and other electronic devices can weaken the signal. For optimal performance, it's recommended to place the speaker no more than 5-7 meters from the TV within direct line of sight.
Using the LG ThinQ app for Wi-Fi control
To fully utilize Wi-Fi capabilities and integrate into a smart home system, an app is required. LG ThinQThis software allows you to control the speaker and TV as a single unit, creating scenes and device groups. Connecting via the app provides more stable control and access to additional equalizer features.
First, you need to add the speaker to the app on your smartphone. Once registered, the device will be available to other users on the same network. LG TVs running webOS may also have the ThinQ app installed, or the feature may be built into the system.
☑️ Setup via the ThinQ app
In some cases, especially with newer models, the TV may automatically prompt you to connect a device found on the network. This happens thanks to the network device discovery protocol. If the automatic suggestion doesn't appear, you can try searching for the speaker using the "Connected Device Manager" menu.
The advantage of using Wi-Fi via an app is the multi-room audio capability. You can stream music to the speaker while the TV is off, or, conversely, use the speaker as part of a surround sound system if the configuration allows. However, for real-time audio transmission from the TV to the speaker, a hybrid method or Bluetooth protocol initiated over the network is most often used.
WiSA technology and wireless surround sound
Owners of premium LG TV models and corresponding soundbars or speaker systems may encounter the term WiSA (Wireless Speaker and Audio). This is a standard developed specifically for transmitting multichannel audio without compression or latency over Wi-Fi frequencies. Unlike standard Bluetooth, WiSA supports transmission of up to 8 channels of high-resolution audio.
This technology requires a special transmitter (dongle) that connects to the TV, or a built-in module in newer models. The speakers must also support the WiSA Ready standard. Setup is performed through a dedicated menu wizard, which guides the user step-by-step through the process of registering each speaker in the system.
| Characteristic | Bluetooth (Sound Sync) | Wi-Fi (ThinQ/Smart) | WiSA |
|---|---|---|---|
| Sound quality | Compressed (SBC/AAC) | High (depending on network) | Lossless (Hi-Res) |
| Latency | Average | Low | Minimum |
| Number of channels | Stereo (2.0) | Depends on the device | Up to 8 channels (7.1) |
| Difficulty of setup | Low | Average | High |
⚠️ Attention: WiSA technology requires the use of WiSA-certified equipment. Standard LG XBoom Bluetooth speakers do not directly support this protocol without a dedicated receiver.
If your goal is to create a full-fledged home theater with rear surround channels, WiSA is the preferred choice. However, for a simple stereo system consisting of a TV and one portable speaker, this standard may be overkill and require the purchase of additional expensive equipment.
Setting up audio settings after connection
Once the devices are successfully connected, you need to properly configure the audio output settings to avoid echo or lip synching. In the LG TV menu, you should find the audio delay settings or AV SyncAutomatic mode often doesn't work correctly with third-party Bluetooth devices, so it's best to set the value manually.
It's also worth paying attention to the digital output format. If an adapter or specific operating mode is used, PCM may be more compatible than Dolby Digital, although it offers less bandwidth for multichannel audio. For a stereo speaker, there will be virtually no difference, but the connection stability may improve.
In the ThinQ app's equalizer menu, you can select a sound profile suitable for your room. The "Movie," "Music," or "Game" modes change the signal processing algorithms. For watching movies, we recommend disabling any surround sound effects on the speaker itself if your TV already processes a surround signal to avoid a muddy sound.
- 🎚️ Adjust the balance between the left and right channels if you have only one speaker.
- 🔇 Disable your TV's internal speakers in the settings if they continue to work.
- 🎼 Select a sound profile depending on the content (movies, sports, news).
- 📉 Check your night mode settings if you watch movies late at night.
Keep in mind that audio quality also depends on the original video content's bitrate. High-definition streaming services require a stable internet connection to avoid buffering interruptions in the audio stream.
Troubleshooting and troubleshooting
Even with proper setup, users may encounter issues. One of the most common is that the TV doesn't detect the speaker. In this case, you need to reboot both devices by unplugging them for 30 seconds. This will reset the network module cache and resolve any temporary software glitches.
If the sound is intermittent or crackling, the problem is most likely Wi-Fi interference. Bluetooth and Wi-Fi operate in the 2.4 GHz band, and they can conflict. Try switching your router to channel 1, 6, or 11, or, if possible, switch your TV to a 5 GHz network while leaving the speaker on 2.4 GHz, although this doesn't always resolve the issue.
Another common issue is audio and video desynchronization. If the AV Sync setting in the TV menu doesn't help, try changing the settings in the source app itself (such as YouTube or Netflix), if such an option is available. Switching the audio format from "Auto" to "PCM" in the digital output settings also helps.
⚠️ Attention: Menu interfaces and item names may vary depending on the TV's year of manufacture and webOS firmware version. If you can't find the item you're looking for, use the settings search (the magnifying glass in the top corner of the menu).
In rare cases, the problem stems from the TV's Bluetooth module being full. If the TV has previously connected many devices, it may stop detecting new ones. Go to the list of paired devices and delete any unnecessary or old devices, freeing up space for the new speaker.
Frequently Asked Questions (FAQ)
Is it possible to connect an LG speaker to a TV of another brand via Wi-Fi?
Direct connection via LG's proprietary protocols (Sound Sync, ThinQ) to TVs from other brands (Samsung, Sony) is not possible. However, if the speaker supports standard Bluetooth receiver mode, you can connect it to any Bluetooth-enabled TV. Streaming audio via Wi-Fi requires third-party transmitter apps on your smartphone or the TV must support Chromecast built-in technology if the speaker is acting as a Chromecast device.
Why does the speaker turn off by itself after a while?
This could be related to power saving settings. Many portable speakers automatically turn off if they don't detect an incoming audio signal for a certain amount of time (usually 15-30 minutes). If you pause a movie, the speaker may "sleep." A weak signal or low battery could also be the cause.
Does connecting a speaker affect image quality?
Connecting a Bluetooth device shouldn't affect image quality in itself. However, if the router is overloaded with large data transfers (for example, 4K streaming) and simultaneously handles the connection to the speaker (using Wi-Fi Direct or similar technologies), micro-lag may occur. When using pure Bluetooth audio, the impact on the video stream is minimal.
How do I reset network settings on an LG XBoom speaker?
To reset network settings, you typically need to simultaneously press and hold the volume up and Play/Pause buttons on the speaker for 5 seconds until the Bluetooth indicator flashes. After this, you need to re-add the device to the LG ThinQ app.
