So, yesterday I updated the recently released Fedora 18, this has been done:

Update 2.20.17-1.fc18.x86_64 @updates
After rebooting today - the sound's gone and Dummy Output is the only device left. So my wild guess would go towards the xorg-x11-drivers .. I tried adding myself to the 'audio' group - but to no avail. It's the usual Intel chipset.
I have no clue where I should begin debugging this, any hints ?
Edit: The older kernel
3.6.11-1.fc17.x86_64 works just fine. It's
3.7.2-201.fc18.x86_64 which is causing the problem.
Edit 2: Today, after booting 3.7.2 up, problem seems to be gone. No clue why.
