A:Answer There are actually four ways to get audio, depending on your soundbar. 1) 3.5mm(headphone) jack 2) optical 3)HDMI ARC 4) Red and white RCA out jacks. Optical would probably be best/easiest to hook up to your sound bar. You will need a Toslink cable like this...https://www.bestbuy.com/site/insignia-6-toslink-optical-audio-cable-black/5895105.p?skuId=5895105. Way over priced here, by the way, check amazone
