Which Kernel?
Which alsa-packages?
Wich distro (sarge|testing|sid)?
Did you build the latest drivers out of alsa-source 1.0.11-2?
What tells cat /proc/asound after a normal boot?
which modules are loaded then?
Are there any mixer settings muted?

Did you tried a live CD (grml|Knoppix|*buntu|Gentoo)?

Best would be to run a Live CD first to exclude a hardware failure
here. And give some Infos about your system and check some audio
apps like moc, alsaplayer, xmms, mplayer......
