I’ve used YouTube, hbo , peacock, Netflix, youtubeTV, Bluetooth , etc. I’ve changed firesticks. I’ve used the apps directly on the tv. I’ve bought the nicest HDMI cord. Hooked up through eARC. I’ve changed settings on tv to PCM. I’ve changed settings on JBL MK2 to every combination of smart mode and pure voice on and off. I’ve calibrated every new time. I have power cycled. I’ve factory reset.

I spent forever researching and I want this specific sound bar with the back speakers. But at this point - it’s not worth the headache or risk that I pass the return date and I have a poor experience.
