Sorry, there was a problem. Please try again later.Hi there. Thank you for sharing your inquiry with us. We understand your question regarding the audio connectivity for your 50UA7700PUB TV. We can confirm that the LG 50UA7700PUB TV does have an optical port (labeled SPDIF (Optical Digital Audio Out) with 1ea listed in the specifications), so you can connect your sound bar using an optical cable. Regarding volume control, this TV features LG Sound Sync and Simplink (HDMI CEC). While Simplink is primarily for HDMI connections to control volume using the TV remote, LG Sound Sync is designed to allow compatible LG sound bars to connect wirelessly via Bluetooth and be controlled with the LG remote. For an optical connection, the TV typically sends a fixed volume signal, and you would usually control the volume directly on the sound bar itself. However, sometimes the TV’s Universal Control feature can be set up to control the sound bar's volume, but this can vary depending on your specific sound bar brand and model. https://www.bestbuy.com/product/lg-50-class-ua7000-series-led-ai-4k-uhd-smart-webos-tv-2025/JJ8VPZW5K4 If you would like us to look into compatibility details for a specific sound bar or need assistance with setting up the volume control after connection, please send us a private message on Social Media @LGUSSupport, and our team will be more than happy to assist you. —Renzo
