F10: new kernel breaks audio (snd-hda-intel)


I have a Dell D830, with F10 fully up-to-date. The kernel update of two days ago ( has broken audio on this machine.

If I reboot on the previous kernel,, audio works like a charm. With the new kernel everything works with no error message, however no sound is output, like the volume is muted or set to very low values. I have checked all volume sliders, both for pulseaudio and alsa and all of them are at maximum and unmuted. I am using the PAE kernel if that matters.

The audio driver is snd-hda-intel, and the output of lspci -v reads:

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)
         Subsystem: Dell Device 01fe

        Capabilities: [130] Root Complex Link <?>
        Kernel driver in use: HDA Intel

Is anybody else having the same problem?
