Public bug reported:

I upgraded from Kubuntu 18.04 to 18.10 beta today, and I noticed I don't have 
sounds. The UI only shows a 'Dummy Device'. After doing a 'sudo alsa 
force-reload', KDE shows the audio device.
When I execute alsamixer in a shell before executing the force-reload, the 
audio card is shown.

My hardware: (from lspci)
