We understand your inquiry regarding the audio connectivity options for your LG 4K UHD TV, model 55UA7050PUB. Based on the official specifications, this model is equipped with one SPDIF (Optical Digital Audio Out) port. It is important to note that this is an output rather than an input, which is the standard design for modern televisions to send digital sound from the TV to an external audio device like a soundbar or receiver. If your external center speaker or audio system has an optical input, you can successfully connect it using a digital optical cable to enjoy enhanced sound. To set this up, please connect the optical cable to the port on the back of the TV and then navigate to your TV's Sound settings to select "Optical Out" as the primary audio source. https://www.bestbuy.com/product/lg-55-class-ua7050-series-led-ai-4k-uhd-smart-webos-tv-2025/JJ8VPZKYK4 If you have any further questions about its features, please contact us on lgdigitalcare@lg.sprinklrsupport.com, and our team will be more than happy to assist you. —Renzo
