The sound and picture are out of sync when screen mirroring from my iPhone 16 Pro to my LGQNED70A6A TV, using the internal speaker. I have tried all the recommended tips in the settings to cure the issue with no success. However, when I isolate the TV from the mains supply for 60 seconds and restart it, the syncing issue is cured but degrades after a day or so. My iPhone software is up to date and there is no firmware upgrade available for the TV. My LinkSys router has a full fibre connection. The only connection into the TV is the mains supply. Any help much appreciated. Thanks in advance.

i am having an issue with my LG OLED77C2 tv that started happening (i believe) once i have updated from web24 to 25. It seems like whenever the tv is displaying a source from any of my four HDMI inputs, while i am watching the screen goes black randomly for a few seconds and it loses audio as well during the black screen. Once this happens the audio usually comes back as soon as the image does, however not always. The audio might dissapear completely. In order to fix that i might need to power cycle the tv or unplug the hdmi input out, wait a little and then plug back in. Moreover, sometimes when the black screen flash happens it cripples most of my native apps on the tv. So if i switch to netflix or youtube right after the black screen flash, both apps populate normally all the video/film options in the main menu but when i try to actually play any of the video/films, they dont play and it is throwing an error. These black flashes never happen when i am watching netflix or youtube. Only when using my hdmi inputs. ive changed brand new high quality cables but that did not fix my issue. For the xbox i was already suing an ultra hish speed 2.1 hdmi cable but ive re placed that as well with a brand new one. ive also changed the tvs main board to a brand new and it still happening. Once the dealer changed the board, the tv was behaving normally without the issue. However after a few days i updated the tv to the latest firmware and this started happening. what do i do?
FYI: I tried EVERY SINGLE option to troubleshoot the issue. Disabled VRR, AMD Freesync, ALLM, HDMI Deep Colour, SIMPLINK, I basically set my tv to display video and audio in the most archaic way just to troubleshoot. Still doing it. I am using an xbox series x on input 1 and a mag520 box on input 3. Does it on both sources. Moreover, in case this helps whenever this happens while on the xbox the Dolby vision/HDR logo appears on the top right right after the video comes back once the black screen is over depending on what settings i have the xbox on. Also swapped to different inputs. Still doing it

Hi, I have a feature request for the sound out setting. I often connect my Bluetooth headphones to the TV. We don't use the internal speaker of the TV, we use the optical sound out setting whenever I don't use Bluetooth. It would make our lives a lot easier if the TV can remember the last sound out setting before connecting to Bluetooth and default back to this setting when the Bluetooth device gets disconnected. At the moment, each time I disconnect the headphones I have to go back into settings and change the sound out setting from internal speaker to optical again.
Thanks and regards
Hubert

TV is a week old and the internal speaker has stopped working when in HDMI ARC + internal speaker sound output mode. The internal speaker itself works fine when in “internal speaker” sound output mode. I’ve checked all the settings that I can and can’t find anything that would correct this issue.

Debuting at CES 2026, LG’s Modular LG Sound Suite With Dolby Atmos
FlexConnect Makes Home Audio Simple and Flexible
SEOUL, Dec. 18, 2025 — At CES® 2026, LG Electronics (LG) is transforming home entertainment with LG Sound Suite, a home audio system that gives consumers unprecedented flexibility. At its core is the H7 soundbar – the world’s first with Dolby Atmos® FlexConnectTM – delivering immersive Dolby Atmos sound that adapts to a room’s layout without complicated setup.
LG Sound Suite works seamlessly with LG’s premium TVs, allowing users to pair any of its wireless components – including the M7 and M5 surround speakers, and the W7 subwoofer – with or without the H7 soundbar for 27 possible configurations. This flexibility means consumers can create the perfect setup for their space, whether starting small or building a full 13.1.7-channel home theater. And when the H7 soundbar serves as the lead device, Dolby Atmos FlexConnect works with any TV via HDMI, giving consumers the freedom to meet their entertainment needs. LG is also bringing Dolby Atmos FlexConnect to its 2026 premium TV lineup and select 2025 models* through a future software update, unlocking even more ways to enjoy Dolby Atmos.
Dolby Atmos FlexConnect delivers the simplest and most flexible way to bring immersive Dolby Atmos sound to your favorite big screen. Enjoy astonishing audio that makes every explosion more intense, every song more life-like, every game day more electrifying and every moment more memorable. Setup has never been easier – it’s flexible and intelligently tuned for your personal listening environment.
Audio is reclaiming its place in the living room as streaming has replaced physical media. Leading platforms now deliver movies, shows, and sports in Dolby Atmos and other advanced formats, making cinematic sound widely accessible. This shift has revived home theater, with consumers seeking immersive audio to match the stunning TV visuals. LG Sound Suite answers this demand with wireless convenience, simplicity and performance, bringing true surround sound back to the heart of the home. With Bluetooth and Wi-Fi connectivity, LG Sound Suite offers seamless pairing for streaming and device integration, making setup as simple as enjoying the sound.
In this regard, LG adds its own layer of innovation to elevate the experience. Sound Follow leverages ultra-wideband (UWB) technology to adjust the listening sweet spot based on the user’s location. When combined with Dolby Atmos FlexConnect, this ensures personalized immersion – so any seat feels like the best seat. Additionally, Room Calibration Pro analyzes acoustic characteristics and applies AI processing to refine the sound for a balanced, room-filling audio experience.
Powering the H7 soundbar is LG’s most advanced processor, the α (Alpha) 11 AI Processor Gen 3 – the same chip that drives LG’s flagship OLED TVs. Bringing this proven technology to audio delivers added performance and intelligence. The processor uses deep learning and its Neural Processing Unit to create sound with remarkable precision. With AI Sound Pro+, stereo audio can be up-mixed into multi-channel surround sound, while AI-powered object separation ensures voices, music and sound effects are clear and balanced. The system also adapts audio based on content type for optimized sound across different genres.
Every component in the LG Sound Suite features Peerless speaker units, a name synonymous with audio excellence for over a century and renowned for high-performance craftsmanship in premium speaker systems. By pairing the simplicity and flexibility of Dolby Atmos FlexConnect with the high-caliber acoustic performance of Peerless speakers, LG Sound Suite ushers in a new era of immersive Dolby Atmos sound.
“Together with Dolby, we’ve made immersive audio flexible for every home, LG Sound Suite is a testament to our shared focus on audio innovation,” said Lee Jeong-seok, head of the LG Media Entertainment Solution Company’s Audio Business Division. “LG Sound Suite combines Dolby Atmos FlexConnect with its wireless modular design and AI-driven tuning, so consumers can create the system they want and enjoy cinematic sound from any seat.”
“Dolby and LG are unlocking a new level of audio flexibility for anyone who wants to enjoy better sound with Dolby Atmos,” said John Couling, Senior Vice President of Entertainment at Dolby Laboratories. “Whether your speakers sit on a shelf or are tucked into a corner, Dolby Atmos FlexConnect fits naturally into any home without the complexity of traditional systems. We’re excited for consumers to experience this new level of audio flexibility and performance.”
LG Sound Suite will be on show during CES 2026 from January 6-9 at LG’s booth. To stay up to date with all of LG’s latest innovations and products for ultimate home entertainment experience, please visit the

Question
Anthony Hanson
New LG OLED 65" Smart TV and new LG Sound Bar. From first setup we're getting a 1 or 2 second sound loss every 15 minutes or so. It was happening with the optical cable. I swapped to HDMI cable and it's still happening. It doesn't happen when using TV speakers. How can I fix this? It happens when using the TV and when playing a DVD on a BluRay player. I haven't tried it yet with a BluRay disc yet. Thanks.
