I am fairly new to Ubuntu, but I have used it for a while, more than 2 months. A couple of weeks ago I did an update. After that I have not been able to get the sound card detected. I have tried a mass of different solutions to no avail, I even upgraded to the latest BIOS firmware and did nothing. A very similar problem is the one found here
I have an Elitebook 850 G6

I have tried removing alsa things, adding them back, a lot of stuff that I could find on the internet, none of which has worked. Any help would be greatly appreciated. I am actually thinking on giving up on Ubuntu if I cannot find a solution here. Pitty really, cause it has worked well so far.
Please also keep in mind that it used to work before the upgrade I did.
Thanks in advance for any help (and stay safe)
