Thanks for this method Ruxolitinib! I went through all your steps and this was the most successful attempt because the speaker appeared in the audio outputs, but after rebooting it disappeared. I had a problem after reinstalling Windows 11, I reinstalled it because Microsoft Store didn't work for me, and I really needed one program, after reinstalling everything worked, but now the problem is with my JBL speaker, after all the steps I took on all the reddits/forums, etc., it at least appears in the list of audio devices in Settings -> Sound -> Additional sound options, it started to appear there, but this is only when it is connected, as soon as I connect it it immediately disappears from there and that's it, you can't find it there, although there is a check mark to show hidden devices and a check mark to show disconnected devices, it is still nowhere to be found, in the device and printer settings it is there, and it is even displayed as a speaker and there is not even a check mark on Handsfree Telephony, I don't even have several "Bluetooth serial ports", all in vain anyway, I'm already thinking about downloading Windows 10 ...
