Hi there. We understand your inquiry about connecting the LG OLED evo C5 4K Smart TV, Model #OLED42C5PUA, to a Samsung Sound Tower. The LG OLED TV, Model #OLED42C5PUA, is designed with multiple connection options and should be able to connect to a Samsung Sound Tower. You have a few options to establish this connection: HDMI eARC (Recommended): Connect an HDMI cable from the Sound Tower's HDMI Out (or TV ARC/eARC) port to the TV's HDMI 2 port, which supports eARC (Enhanced Audio Return Channel). Bluetooth: Use the TV's built-in Bluetooth (v 5.3) to connect wirelessly. Optical Digital Audio Out: Use an optical cable to connect the TV's SPDIF (Optical Digital Audio Out) port to the Sound Tower. https://www.bestbuy.com/product/lg-oled42c5pua-42-4k-oled-ultra-hd-smart-tv-with-a9-ai-super-upscaling-2025/JJ8VPZWHL9 We can guide you step-by-step through the connection process using the TV's sound settings.
