Public bug reported:
I updated my laptop from Kubuntu 14.04 to 14.10 and on to 15.04
yesterday, got quite soem troubles now, most of which are hardware
related. This bugreport mentions the problem that my builtin audio isn't
recognized at all.
Here's the relevant output of 'lspci -vv':

In systemsettings -> Multimedia the only active entry for all types of
media categories is the dummy device. Neither sound card nor auio
configuration are listed under 'configure audio hardware'
Please let me know if I can be of further help to track this issue down,
I'll be glad to help out with additional information.
