Your post before this one had my curiosity piqued at your mention of your soundbar "updating". I wondered how complex these things are. So I pulled up a schematic of a JBL system. Yeah, what a mess. Overly complex and largely digital, with an IC containing a processor, RAM and too many multiplexers (to handle the multiple inputs) for my taste. If I were ever interested in a soundbar, I'd build one myself. Op amps with good skew rates, quality power amps with solid transformers. 30 Watts Class AB. Building a speaker enclosure isn't my thing, so maybe I'd use an existing one.

Back to your issue, it sounds like your system is malfunctioning. Bluetooth is really a crap way to run anything, if you're serious. How's the RCA input?

I’m sure they have a good reason but for the life of me I can’t think of why my speakers would need an update.  Seems fairly simple, just play the sound.

Only time I want it to play via Bluetooth is on the rare occasions I connect my phone to it.  It was originally hooked up with an optical cable/wire whatever it’s called.  It reverted to BT I guess since the optical didn’t work.  I’ll be honest, I didn’t even consider using the RCA jacks(assuming I have them on there) never payed much attention.  I just assumed it was an out dated way of doing things.  It’s currently working.  So next time it quits I’ll try the RCA and see if that works.  Maybe the optical input on the bar or output on the TV is messed up.
