Hi

I have a Dell D830, with F10 fully up-to-date. The kernel update of two days ago (2.6.27.9-159.fc10) has broken audio on this machine.

If I reboot on the previous kernel, 2.6.27.7-134.fc10, 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:

Is anybody else having the same problem?

I didn't have exactly that problem with the 159 kernel.  I was able to play sound but it was slowed down by about 1/3 to 1/2.  I couldn't find a reason, and wasn't sure it was the kernel, but when I, like you, reverted to the 134 kernel sound began working just fine.  I don't use pulseaudio.

The 159 kernel seemed to work fine other than that.

I can report another issue with the snd-hda-intel driver....I am using a Dell Vostro 1400 laptop and using the 159 kernel the lineout does not work.  If the speakers are plugged in, there is no sound whatsoever and I checked every possible mixer setting.  Unplugging the cable to the speakers, however, results in sound coming out of the laptop speakers after a noticeable pause.  Reverting back to the 134 kernel, these issues go away.
