Updated Fedora 18 - no sound devices, just dummy output

Question

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.

Solution 1

The sound drivers are part of the kernel. Try booting into an older kernel to see if your sound device is restored.

Solution 2

after upgrading from Fedora17 to fedora18 using FedUp everything worked fine except the Sound...no sound at all.... so reloaded all ALSA and OSS ... and after all configured Kmix soundmixer settings->Audio Hardware Setup -> profile = Analog Stereo output + Digital stereo (IEC 958)input.... that worked...Fedora18 is cool ....

When booting up 3.6.11-1.fc17.x86_64 everything's restored to normal. Is there anything I should try out now, in order to make sound work with the most recent kernel ?

Dunno. But I'd log a bug on RH's Bugzilla.
