LinuxQuestions.org - Sound card half-working

I'm having a strange problem configuring my sound card.
Sometimes it works, sometimes it doesn't: when I usually start the computer, I can get no sound. If I run system-config-soundcard (on Fedora), I don't find any "PCM device" listed.

But after running alsaconf I can get audio working!

Here's some configuration before running alsaconf:

now... how can I put some order in my computer, so that when I start it, the sound card module are automatically probed?

Thanks for anybody who spends a little time to help an unexperienced user like me.
