OK, so we know that the problem is not limited to desktop applications;
it seems to be a general issue with ALSA.

You can do this:
amixer > before.txt
before you run alsaconf and afterwards you run
amixer > after.txt
and compare the mixer settings with
diff -u before.txt after.txt
to make sure that the difference is not due to some semi-obscure control
that you overlooked.

Please post the output of the following commands (before you run
grep ^Codec /proc/asound/card?/codec*
grep '.*' /sys/module/snd_hda_intel/parameters/*
It would furthermore be interesting to know if the output of the last
one (the module parameters) changes after you run alsaconf.
