bluetooth discovery not working

[Matteo Romiti]

audio quality on my new bluetooth headphones was not ok, so I did the following

sudo apt install git build-essential dkms
git clone https://github.com/jeremyb31/newbtfix-4.15.git
sudo dkms add ./newbtfix-4.15
sudo dkms install btusb/4.0

as suggested here
https://askubuntu.com/questions/1050304/bluetooth-is-not-working-ubuntu-18-04-lts

then the devise discovery was not working anymore and this is what I have now

If your original problem was only about bluetooth sound quality, check the Profile shown in your Sound settings, confirm it is set to A2DP and not HSP/HFP.

[Matteo Romiti (matteo7moh)]

Thanks for replying,

at the moment I care about solving the device discovery problem with the
Bluetooth, which is not working anymore (not only with my headphones, but
with any device).

Kind regards,
Matteo
