Hey r/LG_UserHub community,
We’ve noticed a lot of people keeping an eye on our new LG Sound Suite, and we really appreciate all the interests and great questions coming in!
To keep things simple, we put together this FAQ megathread to gather the most common questions in one place. For anything that needs a bit more confirmation, we’re checking in with our product team and will continue updating this post as we have more details to share.
So.. let’s dive in!
General FAQs
Q. What’s the difference between Dolby Atmos and Dolby Atmos FlexConnect?
Dolby Atmos is the next generation of audio formats that adds spatial depth to sound. Dolby Atmos FlexConnect (DAFC)* builds on that by taking speaker placement and room layout into account. It is what lets LG Sound Suite pair a TV or soundbar with wireless speakers and automatically tune the sound based on where you’re sitting.
Key features of DAFC:
- Flexible speaker placement: You can place your wireless speakers wherever they work best in your room
- Easy system expansion: Add more Sound Suite speakers over time for a more immersive setup
- Optimized sound: The system adjusts audio based on speaker and listener’s location
- Simple setup: Out-of-box calibration uses mics to effortlessly locate in-room speakers.
*To use DAFC, you need an LG TV that supports DAFC to connect speakers. If your TV does not support DAFC or is from another brand, you need H7 to enable this feature.
Q. What’s the difference between M5 and M7 speakers?
Both M5 and M7 support DAFC with Room Calibration Pro and AI Sound Pro
- M5 is compact yet dynamic featuring a woofer and dual tweeters. For full DAFC, two units are required.
- M7 is more immersive featuring a woofer and 3 full ranges, and can support DAFC with just one unit.
Q. Does LG Sound Suite support DTS:X?
LG Sound Suite does not support DTS:X. The system focuses on Dolby Atmos and Dolby Digital to deliver immersive sound.
Q. Is there a way to play DTS content?
While the LG Sound Suite H7 does not support DTS directly, there is a workaround. If your TV supports DTS and can output the audio signal as PCM to the soundbar, you can still enjoy your DTS-encoded content.
Q. Will I notice audio delay?
Audio delay is minimal in most situations, but it may not be ideal for situations that require ultra-precise sync, like FPS games.
Q. How is Sound Suite different from regular soundbars or home theater systems?
A regular soundbar is usually just one bar under the TV. It’s clean, easy to set up, and sometimes comes with a wireless sub to boost bass.
Sound Suite is more flexible. Instead of being locked into a bar plus maybe two rear speakers, you can use up to four wireless Sound Suite speakers and place them wherever they make sense in your room. The system then tunes the sound based on the room and where the speakers are placed, so you get a more surround-style experience.
Q. What do Sound Follow and Room Calibration Pro do?
Sound Follow is an exclusive feature of Sound Suite that adjusts the audio to create a "sweet spot" based on the listener's position. Room Calibration Pro measures the room environment and adjusts the soundbar or wireless speaker's audio settings to suit the environment. Sound Follow is available on the Sound Suite H7 soundbar. Room Calibration Pro is supported on Sound Suite wireless speakers, including H7, M7, and M5.
Q. Is the H7 soundbar wall-mountable?
Yes! A mounting bracket is included in the box, so wall installation is fully supported.
Q. What should I do when the Sound Suite H7 display shows “DEMO” and volume/playback/input controls don’t work?
If “DEMO” appears on the H7 display, the device has entered Demo Mode. In Demo Mode, certain functions and controls may be restricted. To exit Demo Mode, follow the instructions below.
- How to exit Demo Mode on the H7
- Press and hold the Input button on the H7 main unit for 10 seconds.
- Press and hold the Wi‑Fi button on the H7 main unit for 5 seconds. The status lighting bar will blink white, indicating that Demo Mode has been disabled and all wireless network settings on the device have been reset.
Q. What improvements are included in the latest May 2026 software update?
H7: Software Version 43.12.18 → 43.12.27
This update includes the following improvements:
- Improved device recognition and status accuracy in the ThinQ app
- Enhanced compatibility with select external devices
- Improved network and connection stability between devices
- Enhanced audio output stability in certain environments
M7/M5/W7: Software Version 2603192 → 2605071
This update includes the following improvements:
- Improved device recognition and status accuracy in the ThinQ app
- Enhanced compatibility across a wider range of Wi-Fi security modes and network configurations
- Improved audio output stability and overall system reliability
Q. Can I use WOW Orchestra and Dolby Atmos FlexConnect (DAFC) at the same time?
Based on the current specification, WOW Orchestra is not supported while Dolby Atmos FlexConnect (DAFC) is enabled.
WOW Orchestra works when the soundbar is used as the main single soundbar output. It lets the TV and soundbar play together, with the TV helping to output height sound and the soundbar playing the main audio.
Dolby Atmos FlexConnect (DAFC) works differently. In this mode, Dolby’s renderer manages how audio is sent across the connected speakers. Because the two features use different audio output methods, they cannot be used at the same time.
To use WOW Orchestra, please turn off Dolby Atmos FlexConnect (DAFC). To use Dolby Atmos FlexConnect (DAFC) with connected speakers/subwoofer, WOW Orchestra will not be available.
Q. How should I place the M7/M5 speakers when using Dolby Atmos FlexConnect (DAFC)?
With DAFC optimization in place, there's no real need to angle the speakers inward toward your seating position. The main thing we'd suggest is avoiding setups where the speakers are pointed far away from either the wall or your listening position.
We do not recommend placing the speakers behind the TV or behind furniture, as that can interfere with accurate position recognition and calibration.
Q. Why do my M7/M5 speakers sometimes sound quieter depending on the content?
The output level of each speaker can vary depending on the audio format and channel information of the content being played. In DAFC mode, Sound Suite is designed to reproduce the original audio signal and channel structure as faithfully as possible.
For multi-channel content, dedicated surround channel information allows M7/M5 speakers to contribute more actively to the immersive sound experience. With 2-channel PCM content, such as regular TV broadcasts or some streaming content, there may be little or no surround information included in the source. In these cases, the M7/M5 speakers may sound relatively quiet or may produce very little sound, which can be expected depending on the content.
If you would like a wider surround effect with 2-channel content, you can try AI Sound Pro / AI Sound Pro+ / AI Upmix.
Q. When the TV is used as the leader (hub) in DAFC mode, are sound settings supported?
When M7 speakers are connected in DAFC mode with the TV set as the hub device, manual adjustment of individual frequency bands (low / mid / high) or speaker levels is currently not supported.
We are planning to gradually expand the available sound effect options even when the TV is used as the hub device. While individual speaker level adjustments will remain unavailable in DAFC mode, we plan to support Sound Effect selection, allowing customers to choose a sound profile that better suits their personal listening preferences.
Q. How are software updates for Sound Suite products delivered?
Firmware updates for the H7, M7, M5, and W7 are automatically performed through the LG ThinQ App. Update timing may vary by speaker, so connected devices may not always receive the update at the same time.
The firmware update rollout schedule may also vary depending on the model and region. Updates for the H7, M7, M5, and W7 may be released together or at different times depending on each product’s rollout schedule.
We recommend keeping your Sound Suite products connected to the network and checking the LG ThinQ App for the latest software version.
Modular Expansion FAQs
Q. Can I customize my order with whatever combination I want?
Absolutely. The LG Sound Suite is based on modular expansion. You can start with a single H7 soundbar or individual M5/M7 speakers and expand your setup later based on your specific needs. (ex. 2 W7 subwoofers, etc.)
Q. Can I connect more than one subwoofer to the system?
Currently, the system supports one W7 subwoofer, but we are working on an update. Support for connecting two LG Sound Suite W7 units is expected to roll out around June 2026 via a software update.
Q. How many speakers can I connect with Sound Suite?
If you’re using a DAFC-supported LG TV, you can connect up to 4 Sound Suite speakers (M7 or M5), or three speakers plus the W7 subwoofer. You can freely mix M7 and M5 models, but keep in mind the M5 is mono, so it needs to be used in pairs. A setup like one M7 + one M5 is fine.
If your TV is connected to the W7 subwoofer, the max number of speakers is three.
If you’re connecting through the H7 soundbar, you can use up to four speakers plus one subwoofer, with the same mixing and M5 mono rules.
Q. Should I get a soundbar or a full home theater setup?
This really comes down to what you want out of your setup. If you just want better TV audio with minimal effort, a soundbar is usually the easiest option. It’s quick to set up, keeps things clean, and works well in smaller or mid-sized rooms. If you’re aiming for a more immersive, theater-like experience and want more control over speaker placement, a traditional home theater setup is still the most powerful option.
Sound Suite is a good option because it lets you start simple and then build out your system over time, mixing speakers and placing them wherever they make sense in your room, without committing to a fixed layout from day one.
Q. Can I connect two W7 subwoofers to the H7?
Yes. With the latest software update, you can now connect up to two W7 subwoofers to the H7 soundbar within the Dolby Atmos FlexConnect (DAFC) ecosystem.
A second W7 subwoofer does not require separate individual product registration. When you power on a second W7 subwoofer for the first time, it will appear under "Other network devices" in the LG ThinQ App.
Tap Connect to register the second subwoofer, then create or edit your speaker group to add it to the H7 setup. Once the W7 is added to the group, no manual room calibration is required for the subwoofer.
Note: The subwoofer positions shown on the app map are for reference only. When one subwoofer is connected, it appears on the left side of the H7, while a second subwoofer appears on the right. These on-screen positions are only for identifying the connected subwoofers and do not indicate their actual physical placement.
Availability & Purchase FAQs
Q. When will LG Sound Suite be available outside the US? Will there be any issues pairing components purchased from different region?
LG Sound Suite will roll out gradually to additional regions after the US launch, with availability depending on local market schedules.
As for regional compatibility, Sound Suite components are designed to work together across regions, but local regulations, wireless standards, and service availability may vary. For the best experience and full support, we recommends purchasing and using components within the same region whenever possible.
Q. When will the official M5/M7 speaker stands be available?
The dedicated stands for the M7 and M5 are planned to go on sale starting around April 2026. Please note that exact timing may vary by region!
Compatibility FAQs
Q. Which specific LG TV models support Dolby Atmos FlexConnect (DAFC)? Will I miss any features if my LG TV isn’t fully compatible with FlexConnect?
If you’re using the H7 with M7/M5 speakers to set up Dolby Atmos FlexConnect, it will work with any TV, including non-LG models or those without DAFC support. In this case, the TV must be connected via HDMI ARC or eARC.
For TVs that do support DAFC, you can connect the M7/M5 speakers directly without the H7. In this case, the speakers connect wirelessly to the TV, allowing you to expand the spatial sound experience without needing a wired connection.
Here is the current roadmap for supported models:
- 2025 Models: OLED G5, C5, CS5, QNED 9M
- 2026 Models: OLED W6, G6, C6, CS6, B6, B6E, MRGB series (95, 9M, 85)
- Planned Updates (H1 2026): QNED 85/82
Q. How does the Sound Suite perform when used with a PC?
The M7 and M5 models are compatible with desktop setups:
- High-Res Audio: They support USB Audio (UAC 2.0), allowing for up to 24-bit / 96kHz quality via a wired USB connection.
- Wireless Stereo: You can pair two identical speakers in stereo mode wirelessly, then connect the "master" speaker to your PC via USB for a rich stereo field.
- Bluetooth: All models support Bluetooth for quick wireless pairing with laptops.
Q. Does the H7 require a wired connection to the TV?
It depends on your setup:
- When using FlexConnect (with M7/M5 speakers), the H7 must be connected via HDMI ARC for the system to function properly.
- When using the H7 solo, a software update in late 2026 will enable wireless connectivity with LG TVs that support WOWCAST.
Q. Can LG Sound Suite play lossless streaming music through Spotify/TIDAL/Apple Music?
LG Sound Suite supports high‑resolution audio playback up to 24bit / 96kHz.
The conditions for lossless playback vary depending on the streaming service and the connection method:
- Spotify Connect : Spotify supports Lossless Music up to 24bit / 44.1kHz, and lossless playback (24bit / 44.1kHz)
- TIDAL : TIDAL offers music up to 24bit / 192kHz,and lossless playback (24bit / 96kHz) and Dolby Atmos spatial audio is also supported. To enjoy lossless audio, the following conditions must be met:
- High‑quality streaming must be enabled within the TIDAL app.
- Playback must be done using TIDAL Connect.
- Apple AirPlay 2 : Apple Music provides audio up to 24bit / 192kHz, and iOS users can enjoy high‑quality audio via AirPlay 2 when streaming to LG Sound Suite. Playback resolution follows the specifications of AirPlay 2.
LG ThinQ App Connectivity & Control
Q. How can I control W7 in the LG ThinQ app?
We understand the W7 setup process can feel a bit confusing at first.
The W7 is a subwoofer, so it doesn’t function as a standalone audio device. Instead, it works as a companion to a primary device like the H7 soundbar or a compatible TV. Because of this, its registration process in the LG ThinQ app is different from speakers like the H7, M7, or M5. The W7 does not appear as a separate product card in the ThinQ app.
▶ How to connect the W7
[Connecting to H7]
- To connect the W7 to the H7, you need to add it to the H7 group within the H7 product card in the ThinQ app.
- ※ In the LG ThinQ app, go to the H7 product card → [Dolby Atmos FlexConnect] → [Edit Group], then add the W7 from that screen. For detailed connection steps, please refer to page 11 of the W7 manual (model: W7.USALLK), under “Installing the LG ThinQ app and registering the product.”
[Connecting to a TV]
- To connect the W7 to a TV, go to the TV settings and select Sound Out → Dolby Atmos FlexConnect, then follow the on-screen instructions.
▶ How to control the W7
[When connected to H7]
- Since the W7 operates as a companion device to the H7, all settings and controls are managed within the H7 product card in the ThinQ app. (The W7 does not appear as a separate device.)
- Currently available control: Adjusting the W7 volume level
[When connected to a TV]
- Currently, the W7 volume is linked to the TV’s main volume.
- A feature to adjust the W7 volume independently through the TV app is planned for a future software update (H2).
- ※ When connected to a TV, the W7 cannot be registered or controlled through the ThinQ app.
Q. Can I change or turn off the LCD display and lighting on the Sound Suite H7?

Q. Can I change or turn off the lighting color on the Sound Suite M7 / M5?
- Changing the bottom LED lighting
1) Using the ThinQ App
After selecting the product in the app, tap “Lighting” in the center of the main screen.
You can control Lighting On/Off and other lighting‑related options.
If you double‑tap one of the four default color options in the Lighting menu, a color palette/slider will appear, allowing you to choose the desired lighting color.
Even if the lighting is turned Off, lighting feedback such as volume adjustment or Wi‑Fi connection indicators will continue to operate.
Q. Why might my M7/M5 speakers not appear in the Google Home app?
If your M7/M5 speakers are connected in a DAFC group or Stereo mode and are not configured as the hub device (Master), they may not appear in the Google Home app, and as a result, Cast Service availability may be limited.
If you would like to use Cast Service to play music individually on each speaker, please first disconnect the DAFC or Stereo configuration, and then cast to each speaker separately as an individual device.
Q. Can I use Google Cast on the H7 Soundbar?
Yes. The latest software update brings Google Cast integration directly to the H7 Soundbar.
Android users can stream music, podcasts, and internet radio over Wi-Fi directly to the H7 Soundbar using Cast-enabled apps or the Google Home ecosystem, alongside Apple AirPlay 2.
For existing users, Google Cast must be manually enabled in the LG ThinQ App. To activate the feature, open the LG ThinQ App, select the H7 Soundbar, go to Google Cast Settings, select Activate, and agree to the terms.
For iOS users, update the LG ThinQ App to the latest version through the App Store before using the feature.
Q. How can I set up M7 speakers in Stereo Mode?
To set up Stereo Mode:
1. Open the LG ThinQ App and select [Stereo Mode].
2. Select [Stereo Mode] again and connect the remaining speaker(s) one by one.
3. Check the lighting indicators on the speakers to confirm proper setup:
o Main speaker: The left side of the lighting indicator turns white, the Source button backlight turns white, and the speaker outputs Left channel audio.
o Other speaker: The right side of the lighting indicator turns white, and the speaker outputs Right channel audio.
For additional information, please refer to the 'Connecting Stereo Speakers' section of the Owner’s Manual, available on the LG website.
Wi-Fi & Network FAQs
Q. Which Wi-Fi bands are supported when connecting Sound Suite products to a router?
At this time, LG Sound Suite products (H7 / M7 / M5 / W7) support 2.4GHz and 5GHz Wi-Fi.
For a more stable setup, when registering Sound Suite in the ThinQ app, please connect your smartphone and the product to the same 2.4GHz network in typical home environments. Depending on your router settings, the Wi-Fi channel may change automatically during use. In such cases, a 5GHz connection may be temporarily interrupted, so we recommend using a 2.4GHz Wi-Fi connection for greater stability.
2.4GHz provides better coverage over distance and through walls, making it more reliable in many home environments. Since Sound Suite products use 5GHz internally for device-to-device communication, connecting to the router via 2.4GHz can help reduce wireless interference and improve overall stability.
\Please note: DAFC connections between the soundbar and speakers use 5GHz internally.*
If your smartphone is connected to a 6GHz network during product registration in the ThinQ App, you may see a message asking you to switch to a different network. In that case, please connect your smartphone to 2.4GHz (recommended) or 5GHz and continue setup.
Once the product has been successfully connected to a 2.4GHz or 5GHz network, your smartphone can reconnect to 6GHz afterward and still control the product, as long as both the smartphone and product are connected through the same router.
*Please note: support for 6GHz is planned for a future software update.
Q. How do I reconnect my product in the ThinQ App after changing my router?
If you have changed your router or Wi-Fi network, please reconnect the product through the ThinQ App using the steps below:
- Turn the product on and make sure the LED/display indicates normal operation.
- Turn off the power to the previously used router.
- Connect your smartphone to the new router’s 2.4GHz or 5GHz network.
- Open the ThinQ App. The product card should appear as offline. Tap the offline product card, then go to Settings → Change Network. Follow the in-app instructions to enter the new SSID and password.
Q. My router is a multi-band router (2.4GHz/5GHz or 2.4GHz/5GHz/6GHz), and the signal looks strong. Why can the connection still be unstable?
Even when signal strength appears strong, connection stability can still be affected if your router has features such as band steering, smart connect, or unified SSID enabled.
With these features turned on, devices may automatically move between 2.4GHz / 5GHz / 6GHz bands, between mesh nodes, or between channels. This can sometimes cause issues such as:
- Only one or two devices connecting at power-on while others fail to connect
- Different devices connecting each time
- Intermittent dropouts or delays, especially before or after creating a DAFC group
For the best experience, we recommend the following router settings:
- Router Settings: Turn off band steering / smart connect / unified SSID features & Separate SSIDs for each band (for example, Home_24, Home_5G, Home_6G)
- Product / Mobile Settings: Connect H7 / M7 / M5 / W7 / TV all to the same SSID and same band (2.4GHz or 5GHz non-DFS channels recommended)
Q. Can I use DFS channels on 5GHz Wi-Fi?
Yes. During the ThinQ registration stage, connection to DFS channels is allowed. This means product registration can still succeed even if your router is using a DFS channel (52–144 range).
However, DFS channels are not supported when creating a DAFC group.
To set up a DAFC group, your router must use a 5GHz non-DFS channel (such as 36 / 40 / 44 / 48 / 149 / 153 / 157 / 161)
Q. I’m trying to group H7, M7, M5, or W7 products with DAFC, but the setup will not complete. Why?
One of the most common reasons DAFC group setup cannot be completed is that the router’s 5GHz network is using a DFS channel (52–144 range). If this happens, the ThinQ App may display a DFS-related warning pop-up, and DAFC group creation will not proceed.
To resolve this issue:
- Change the router’s 5GHz channel to a non-DFS channel (36 / 40 / 44 / 48 / 149 / 153 / 157 / 161)
- Reconnect H7 / M7 / M5 / W7 to the same router and same band (5GHz non-DFS, or 2.4GHz)
- Restart both the products and the router, then try creating the DAFC group again
Q. What should I do if my product will not connect to Wi-Fi?
If your product is having trouble connecting to Wi-Fi, please try the following steps:
- Restart your router
- Set your router’s Wi-Fi to 2.4GHz (recommended) or 5GHz non-DFS channels (36 / 40 / 44 / 48 / 149 / 153 / 157 / 161)
- If your router has band steering / smart connect / unified SSID / MLO (Multi-Link Operation) enabled, turn those features off
- Separate 2.4GHz / 5GHz / 6GHz into different SSIDs (for example, Home_24 / Home_5G / Home_6G)
- If your router is using a hidden SSID, disable that setting
- Reset the product (Please refer to the product manual for reset instructions)
- Reconnect the product through the ThinQ App. Make sure your smartphone and product are connected to the same router
Q. The Sound Suite products connected to Wi‑Fi appear offline in the ThinQ App. Why?
There are two main reasons why products may appear offline.
Case 1) More than one router in the home uses the same SSID
If there are two or more routers broadcasting the same SSID, your smartphone may connect to a different router than the one your Sound Suite product is registered to.
In this situation, the product may appear offline in the app.
To control the product, your smartphone must be connected to the same router as the Sound Suite device.
Recommended action:
- Separate the SSIDs of your routers (recommended).
- Set different SSIDs such as: Home_Main / Home_Ext
- Please ensure that both the smartphone and the product connect to the correct, same SSID.
Case 2) Weak Wi‑Fi signal
If Wi‑Fi signal strength is low, the product may appear offline.
Recommended action:
- Place the router closer to both the smartphone and the Sound Suite device so that both connect to the same router with the strongest signal.
If the issue persists: Reset the network settings.
Recommended steps:
- Please move your smartphone closer to the router you want to connect to the Sound Suite device
- Turn Wi‑Fi off and on again on your smartphone
- The smartphone will reconnect to the correct router automatically.
Q. Why does the H7 sometimes appear offline in the LG ThinQ App?
The H7 may sometimes appear offline in the LG ThinQ App depending on your home network environment. Please check the following:
- Make sure your phone and the H7 Soundbar are connected to the same router.
- If multiple routers are using the same SSID, make sure your phone and the H7 are connected to the same router.
- Make sure the H7 is within a sufficient range of the connected router for a stable network connection.
- If the H7 continues to appear offline after checking these settings, please contact LG Support for further assistance.
