Somewhere in there, you should see 1008.0 stream across the sound bar readout.
I would expect your sound bar already to have it. That’s a July 2019 firmware.
When you do the update, you should see “updating” or something like that scroll across the readout.
If the firmware is already up to date, the sound bar might not go through the update process. I don’t recall on that.
