Does anyone have a solution for me?

[zezollo]

I post this in case someone is looking for a similar help; it's extremely complicated to find help on that topic so far; but in a completely similar situation, this seems to have solved my problem:

Code: Select all

sudo dpkg-reconfigure bluez
sudo dpkg-reconfigure linux-sound-base
