I'm about to break something, it's so frustrating. Just wanted to watch a movie, but nope.

I have a Samsung Soundbar that uses an optical cable and a Xiaomi TV 43". It worked before I updated the stupid TV.

I've pulled every other cable out, put speakers on the TV to S/PDIF. I've turned the TV off and on, pulled out the TV and back on. No problem with the Soundbar, just TV. Help me before I'll just break the thing.
