Bug Description
I am using kubuntu LTS 18.04.
This morning I was promped to update the kernel to the 4.15.0-99-generic.
After the upgrade I did not manage to get any sound. I checked everything, pavucontrol, alsamix, everything was in order, the streams showed as if they were playing, however I couldn't get any sound from the speakers headphones and I could not get any sound recorded either.
I then rebooted with the previous version of the Kernel, and have my sound back without doing anything at all.
