Adapted from another post:

Open a console window (the "clam shell" icon on taskbar) and use the command su, then enter the root password. Next, enter the shell command /etc/init.d/alsa-autoconfig to have the sound devices created for alsa. Then open the file /etc/init.d/bootmisc.sh with an editor and add the line aumix -w 75 -v 75 near the bottom of the file to set the default volume levels at boot.

There are a number of other threads on this, as well -- so search on ALSA HD install for more, if you need it.
