Can anyone help?

After the recent update to Android TV 9.0 on my Bravia KD-49XD8305 it appears it will no longer support the dongle that connects to the Subwoofer. It has worked perfectly for the last few years with other updates to the OS.

It will now not sync with the subwwofer, what ever I try to do. I have reset the TV, reset the USB sender/dongle and the Subwoofer too, all with no sucess.

I have read on the USA community board someone else has had the same problem. I doubt I will be able to roll back to Android 8, so waiting on a fix from Sony I guess.

Unless someone has a fix?
