The fact that you have an hda-intel card triggered some thoughts. In
the kernel documentation for sound, the following models are reported
for your card:

It is possible that the alsa configuration got the model for your board
wrong. You could try the following process.
As root, modprobe --ignore-install snd-hda-intel model=asus-p5q
As user, try playing the sound that sounds bad, see if it sounds better.
Repeat with all of the above, starting with the most likely (the asus
models).
When you find a model that sounds good, you can either modprobe it each
time you restart your computer or you can add a file called something
like alsa.conf (name isn't important, being in the folder is)
to /etc/modprobe.d so it will be loaded automatically on startup. In
that file put
options snd-hda-intel model=<best model you found>
