Colleagues,

I am not sure but think an update caused this problem. I have "dummy Sound output" (basically no audio in the PC) and tried several commands on the posts with no luck.
This is the system I have (Ubuntu 18.04.1 LTS)

• Processor : Intel core i5-8400 CPU @ 2.8 GHz x 6


• Graphics : Intel HD Graphics (Coffeelake 3x8 GT2)


• GNOME : 3.28.2


• OS : 64 bits

Here are some commands

lshw -C multimedia

santi@santi-desktop:~$ sudo lshw -C multimedia
