So, it depends on snd, snd-pcm, snd-hda-codec, snd-hda-controller (if I
didn't miss any). The first entry is the name of the module, the second
is the size, third is number of modules that are dependent on it, and
the rest are a list of dependent modules. Try to add the ones I listed
(I'm not sure about the order, but probably the order I listed them in)
before the line that loads snd-hda-intel.

Which logs do you suggest? (I am only medium grade familiar with the
sysadmin tasks of Linux. Not a pro or a guru.)
/var/log/kern.log would be a prime candidate :)
Reboot your system. Make sure *not* to load snd-hda-intel. Take a look
at kern.log, and examine the parts that have messages from the sound
subsystem. Look for errors/warnings/etc. Open a second terminal, and run
"tail -f /var/log/kern.log", and see what messages are then added when
you load the module in your first terminal.
It might be easier for you to read if you, after running "tail
-f /var/log/kern.log" and getting the last few messages, hit enter a
couple of times to get a few blank lines between the last message from
the kernel so far and the first message you get when loading the module.
Or just look at the time stamps.

This line was the result of trying to use the volume control with no sound:

I couldn't spot anything before the modprobe that is relevant to sound,
including hardware detection or loading of driver modules. Heres a
