Hey, just a heads-up on a pretty big mess with Samsung’s 900 Series soundbars (like the Q930D). The latest 10.20 firmware update seems to have completely bricked them—stuck in TV eARC mode, totally unresponsive to buttons or remotes.
There are tons of reports on Samsung forums, Reddit, and even YouTube, but so far, no fix or real acknowledgment from Samsung. This could be thousands, maybe tens of thousands of devices affected, and people are just left with expensive paperweights.
