Hello there, Aj. We understand your inquiry about connecting external speakers to your LG 24LQ520S-PU TV. You can indeed enjoy enhanced audio by hooking up a soundbar or home theater system. First, locate the HDMI port labeled “ARC” (Audio Return Channel) on the back of your 24LQ520S-PU. Connect an HDMI cable from that ARC port to the ARC input on your soundbar or A/V receiver. Next, go into Settings > Sound > Sound Out on your TV and select HDMI ARC to ensure audio is being sent to your external device. This will allow your external speakers to play all audio from the TV. As a troubleshooting step, if you hear no sound after connecting, double-check that you’ve enabled HDMI ARC in both the TV’s audio settings and the soundbar’s input source. Also, verify that the HDMI cable is fully inserted into both the ARC port on the TV and the ARC-designated port on your external speaker system. Ensuring both devices are powered on and set to the correct input mode often resolves most connectivity hiccups. If you’re using a soundbar without HDMI ARC, you can also connect via an optical audio cable (Toslink) from the Optical Digital Out port on the TV to the Optical In on your speaker—then select Optical as the sound output in Settings > Sound > Sound Out. https://www.bestbuy.com/site/lg-24-class-led-hd-smart-tv-with-webos-2022/6506779.p?skuId=6506779 For any additional assistance—such as checking firmware versions or walking through advanced audio settings—please send us a private message on social media @LGUSSupport and our team will be more than happy to explore possible solutions.
