Luckily, I did have an older version of modules.conf. But they were
both pretty much the same - at least as far as the Intel sound driver
was concerned.

There was one weird thing (that was in both the old and new versions).
It had this line which I don't really understand:

remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || :
; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

I tried it both with and without that line, but it seems to make no difference.

This is a desktop (Dell Dimension 5100), not a laptop. Googling for
the chipset shows that many people have had similar problems. Which
is, I suppose, comforting in one way :-)

  $  sudo grep hda-intel /var/log/messages.1
  Jul 21 12:07:52 giles kernel: hda-intel: no codecs initialized
  Jul 21 12:20:29 giles kernel: hda-intel: no codecs initialized
  Jul 21 12:28:25 giles kernel: hda-intel: no codecs initialized

Those times correspond to the reboots I did yesterday trying to get
this to work.

Thanks, but I don't really want to spend the next few hours trying
random options that I don't really understand. Especially given that
this worked fine under FC6.

I've tried Googling for this, but I can't find a reference to the
snd-hda-intel options. Do you know where I can find them online?

Cheers,
