I have the same problem, I guess it applies to everyone on the latest firmware version.
What I find more annoying is how slow the volume changes when you turn the wheel on the speaker. You have to spin it like crazy to lower the volume by a few db.
Also, mine often automatically switch to Bluetooth when a connected phone is nearby, and don’t always turn on when I turn on the tv.
It’s weird, they told us that the new update process allows for faster firmware updates, but it’s been quite a while since the latest update.
