I am pretty much out of ideas now. You could do some general poking
around to compare the situation between the first, successful boot and
the second one. For example:
cat /proc/modules | cut -f1 -d " " | sort > modules1.txt
Then after the reboot save the output of the same command as
"modules2.txt" and use diff to compare the two lists of modules.
If you use an initrd you could try to build the sound modules into it.
If that all fails then you need to attract the attention of someone who,
contrary to me, actually has the same soundcard. I would start a new
thread and make sure that "ATI SB450 hda_codec" is prominently visible
in the subject line. (Many people tend to ignore threads which have such
an unspecific subject as the present one.)
