I have an intel NUC machine connected to my TV. After the last 13.04 kernel update (two days ago) the sound stopped working.
I haven't changed the sound config as far as I know, so it should be a standard unity/pulseaudio set up.
The sound setting control panel shows only DummyOutput.
Normally it should show Intel HDA. It affects the two user acconts on the machine.
The kernel modules appear to be loaded ok
