I have an LG 55UN74003LB smart TV running webOS 5.2.3-252113 with firmware version 3.23.45 and there is a pretty oldschool Samsung HT-DS400 5.1 home cinema system via opticla cable.
Audio cutting in and out constantly when I am playing media that is utilizing the WebOS (e.g.: TV's Youtube app, Netflix, screenshare from mobile, playback from USB attached external drive).
The sound is however flawless when I am using my PS4 or media-box that are connected via HDMI to the TV.
I tried all the possible combinations of the digital sound output (auto, PCM , passthrough) and the format of the audio (MPEG, Dolby Digital/Plus, auto, HE-AAC) with no luck.
Furthermore I purchased a Panasonic HDMI ARC exteactor and diverted TV audio to HDMI ARC port but the outcome was the same:
Flawless audio from mediabox and PS4 and cutting in/out when using TV for playback.

This leads me to beleive that cabling and my Samsung 5.1 sound system could not be the issue,
but there might be something wrong with the TV... possibly firmware issue or something.
Has anyone faced the same, and if so, does a relatively easy fix exists?

  UPDATING YOUR FIRMWARE
  
  The firmware that powers your LG Ultra HD 4K Smart TV with webOS should be updated from time to time to enhance your experience and improve its operation. Thankfully, this can be done easily and quickly, right at home.
  Watch this quick video to learn more. Or follow the easy steps below to get started.
  
  HOW OFTEN DO I NEED TO UPDATE MY FIRMWARE?
  Firmware updates don't happen frequently, so you should be fine checking for updates every other month.
  HOW DO I CHECK FOR, AND DOWNLOAD, AVAILABLE FIRMWARE UPDATES?
  Before you do anything, make sure you have an Ethernet cord connected directly from your router to your television. Wireless Internet connections are not reliable enough for firmware updates.
  Use this diagram if you need help getting set up:
  
  ONCE YOUR TV HAS A WIRED CONNECTION, DO THE FOLLOWING:
  Press the MENU Click SYSTEM SETTINGS Then ABOUT Then SYSTEM UPDATES You'll be advised that your system is currently up to date or requested to select CHECK NOW for the latest update. If a new version is available, it downloads automatically. FIRMWARE UPDATES WILL ALSO UPDATE LG ULTRA HD 4K SMART TV AND LG APPS AT THE SAME TIME.

- Enabling usb recording and live tv
  By Hblone
  
  Hallo, I bought a 55un74006LB smart tv in Italy. It seems not to have usb recording capabilities, according to the information on the italian website, but the UK site declare it has. I think it's the same product with the same functions, so how can I turn the live tv and usb recording on? I think I found the options in the service menu but I cannot change the values. Any suggestion?
- LG SMART TVS TO GET STADIA CLOUD GAMING IN LATE 2021

  LG Smart TVs to Offer Amazing Stadia Gaming Experience Complete with Immersive
  5.1 Surround Sound for Stadia Pro Gamers in the Second Half of the Year
  
  SEOUL, Jan. 11, 2021 — LG Electronics (LG) announces a planned partnership with Google to bring Stadia to its latest webOS smart TVs in the second half of this year. After Stadia comes to Google TV, LG will be the first TV manufacturer to natively support Stadia gameplay via webOS.
  LG is demonstrating its commitment to supporting premium gaming on its state-of-the-art displays, made even more compelling with support for 4k and 5.1 surround sound for Stadia Pro users. Stadia on LG TVs will allow customers to instantly play hit Stadia games such as Cyberpunk 2077, NBA 2K21, Assassin’s Creed: Valhalla and Watch Dogs: Legion with just a Stadia controller and no additional hardware or game downloads required.
  LG plans to have the new service launched within the second half of 2021 on LG Smart TVs as a downloadable app from the LG Content Store in countries where Stadia is available. Stadia already offers more than 130 games with more being added regularly. Games can be purchased individually or gamers can claim a regular cadence of games to be played for free with a subscription to Stadia Pro, which includes exclusive discounts and up to 4K resolution. Exhilarating gaming with immersive 5.1 channel surround sound and support for up to 4K HDR and 60 FPS makes the Stadia platform a compelling choice for anyone looking for a great gaming experience without the need for an expensive, dedicated gaming console.
  And when it comes to gaming, it’s hard to beat the advanced combination of Stadia and LG OLED TVs. LG OLED’s self-lighting pixels ensure best-in-class HDR picture quality with deep blacks and extremely accurate colors. LG became the first company to launch HDR-capable 4K OLED TVs in 2015 and content on LG OLED TVs – both streaming and externally stored – benefit from the display’s fast 1ms response time, outstandingly low input lag without experiencing any loss in picture quality.
  “Supporting Stadia on LG TVs is our commitment to customers that gaming is an increasingly important feature expected by LG TV owners,” said Lee Sang-woo, senior vice president of corporate business strategy at LG Electronics Home Entertainment Company. “Stadia is changing how people access their favorite games and by providing webOS compatibility, we’re making an early commitment to the platform.”
  LG’s perfect-for-gaming LG OLED TVs, new LG QNED Mini LED TVs (with the company’s propriety Quantum Dot NanoCell Technology and mini LED backlighting) and upgraded LG NanoCell TVs will be on display in during CES 2021 starting January 11.

  * At time of launch, Stadia available only on LG smart TVs running webOS 6.0. LG webOS 5.0 TVs will receive the service later this year.
