• Yes the TV has an optical S/PDIF out. You can also configure the the audio settings within the TV to pass through Dolby Digital/DTS if supported on your sound bar.

• This TCL Roku TV can connect to external speaker through HDMI ARC, Optical Audio Out, or the 3.5mm Headphone jack. To use the optical port, you would simply want to connect one end to the TV and the other to your speaker. For best performance, you would want to mute the TV speakers by going to Home>Settings>Audio>Speakers>OFF. Hope this helps! Thank you, TCL Customer Support
