FYI - I'm seeing a problem with the 2.6.28-3 kernel. For some reason
there's no sound coming out of either the speakers or the headphones on my
laptop (Dell Precision M4400) after the upgrade.
Sound module is snd-hda-intel. I checked volume is up, mute is not on, yada
yada, but no sound coming out. Problem goes away as soon as I downgrade the
kernel.
Anyone else seeing this and/or have any idea what the problem might be?
Maybe there's a regression in your soundcard autodetection? Do you
pass any "model=" parameter to snd-hda-intel in /etc/modprobe.conf?
Anyway, there have been a couple of commits in that driver, if you
want you can track them searching for "alsa: hda" in the changelog
(http://kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.28.1).

Thanks for the info.
No, I don't pass any model parameter, partly because I didn't know about
this parm until recently, and partly because I'm not sure what the
correct value should be. ("head -n 1 /proc/asound/card0/codec#0" says
"IDT 92HD71B7X", but I'm not sure where to go to look up the model
number from that.)
Will check the change log and see what's of relevance.
Thanks,
DR
