After my initial email to Skyworth in January, followed by a few exchanges with their support team, Skyworth contacted me today with a firmware update and installation instructions for the SS586 soundbar.
I successfully installed the update and am currently testing it under different scenarios...
Can be anything, YouTube, Netflix, Prime, Plex. Even when the input is changed to the Xbox that is connected. When nothing is happening on the Xbox for about 20 minutes it shut down.
I wished this worked. Still have this issue.. I actually timed it. 20minutes. I have it connected to Skyworth TV as well. The menu is a bit different. Switched off anything with auto shutdown or sleep mode and it still does it
