Sound card worked, now it doesn't

[techlists@techgod.net]

When I installed Potatoe, the sound card worked perfectly.  I set it up so my user worked fine.  I upgraded to woody, and still the user sound worked fine.
I upgraded to 2.4.17, now root can do sound, but the user cannot.

I compiled the sound driver into the kernel, and like I said root works fine.  I checked the groups file, it's correct.  My syslog shows this when I log in as the user:

Jan 11 22:14:00 Agamemnon modprobe: modprobe: Can't locate module sound-slot-1
Jan 11 22:14:00 Agamemnon modprobe: modprobe: Can't locate module sound-service-1-0
Jan 11 22:14:00 Agamemnon modprobe: modprobe: Can't locate module sound-slot-1
Jan 11 22:14:00 Agamemnon modprobe: modprobe: Can't locate module sound-service-1-0


What are those modules, and how do I install them?
