The Intel HDA audio supports many different configurations. Some of
these are know and set automaticly by the driver. Others require
that you add an option in modprobe.conf. If you still have a copy of
your FC-6 modprobe.conf file, compare it to the F-7 version - there
may be options listed in FC-6 that are not in F-7.
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.
You may also want
to do a Google search for the ALSA on your laptop to see what
options others have used to get all the devices shown in the mixer.
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 :-)
You should look in /var/log/messages and see what it messages are
generated when the sound modules are loaded.
$ 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.
Here is what I have in modprobe.conf for my Toshiba - you can try it
and see if it helps...

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.
There are a bunch more model options, but I do not have the
reference for them handy right now.
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,
Dave...
