I can’t get an onn soundbar and subwoofer to link together after the sub stopped working. I’ve tried a bunch of stuff. Anyone know anything about this? It’s the 36” 5.1 with sub and rear speakers from Walmart for $169. I’ve tried linking after leaving them unplugged for 30 min. Unplugging my modem/router. Putting them right in front of one another. Unplugging everything but the power from both. Idk what else to try.
