Please help me in connecting my wireless headphone "Sennheiser HD 4.40 BT" to my laptop running with "Ubuntu 18.04.3 LTS".
I managed to pair the headphone with my smartphone in just 2 seconds (so there is no problem with the headphone)
I managed to connect my laptop to my smartphone easily too.
I am certain that the problem is not hardware-related. I followed all tutos on internet showing what they're claiming to be "solutions" to bluetooth issue in ubuntu 18.04 but I couldn't connect to the headphone.
My problem is that bluetooth on ubuntu is not detecting the headphone and instead it is displaying a list of discovered devices consisting in my smartphone and a bunch of "unknown" devices (grayed out)
Any explanation/solution to this madness ?
