Bluetooth Headphones not Connecting

[kindoflame]

I got some new Bluetooth headphones and an USB Bluetooth adapter. I installed Wine, downloaded the adapter's driver (double-checking the hardware version to make sure it was the right one), and ran the setup.exe file using Wine. I now have two new symbols on my taskbar. The first is the Bluetooth symbol and when I click it a small window simply called Bluetooth appears. The other is a light grey circle with diagonal slash (almost did not notice it at first). When I click that a bunch of Bluetooth options ("Turn Bluetooth Off", "Set Up New Devices", etc.) in a menu appear. As far as I can tell, Bluetooth on computer now works.

However, my headphones cannot connect. I can connect the headphones to my phone, so they cannot be the problem. This article says bluetoothctl can help, but it didn't for me. This thread mentioned that installing Blueman, but again I saw no change.

Does anyone have any advice?

First check in terminal mokutil --sb as Secure Boot needs to be disabled, then in terminal do

sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-5.15.git
sudo dkms add ./bluetooth-5.15
sudo dkms install btusb/4.1

Reboot

Did that, but on when I did sudo dkms install btusb/4.1 I got an error:

Use Update Manager, view menu/linux kernels, click 5.15 on the left and install the newest 5.15 kernel, reboot and then try the

Installed the newest 5.15 kernel, rebooted, ran sudo dkms install btusb/4.1, and then tried to connect the headphones. Still not being recognized. I also noticed that the grey circle with a diagonal slash is gone from the taskbar.

Does anyone have any other ideas on how to help? Should I try returning this Bluetooth adapter and getting a different model?

[jtamark]

Do you have any other bluetooth devices, to see if the computer can interface or recognize them?

Perhaps check if your phone can bluetooth with the your computer.
