i'm assuming you mean the alsa init script.
did you look in the logs (eg /var/log/syslog) for why it failed?

maybe you could tell us what distro and software versions you are
using, together with the output of:

lspci -v

lsmod

service alsa status
	(or whatever it is on your distro)

cat /var/log/syslog | grep -i alsa
	(for the last boot)




also read the documentation for your card on
http://www.alsa-project.org

and the quicktoots:

the archives for the alsa-user list might also be instructive...
