I bought my Roku Soundbar directly from the Roku website. Today, I bought an Onn Roku Subwoofer from Walmart but it will not pair with my soundbar. My soundbar is up to date, Ive unplugged everything and plugged it back in. I even did a factory reset on my soundbar. Is there anything else I can try or should I just return it? Everytime I try to pair the subwoofer it say no subwoofer found.
