Try deleting (or better, renaming) the alsa settings file - in my system
(Gentoo) its in /var/lib/alsa/asound.state. Its likely that some duff
values are muting the sound so that the soundcard gets upset on boot.

When I had this problem, I just had to set things up with alsamixer from
the command line and then restarted alsa via the "/etc/init.d/alsasound
restart" so the new values got saved and then it all remained working
after a reboot.
