Description of problem:
Machine: F-S Esprimo p5600 Dual AMD x86_64. Same problem on almost every singel distribution I've tried and over two different AMD CPU's. The only way to get partial sound support, is by enabling OSS and use the front installed jack. Jack in the back doesn't work in OSS either. 

A very disturbing observation is that I think this issue has been present for a long time, and never been fixed because the bugs become closed as the version number changes. So I've tried to upgrade the severity to see if somebody can give this issue the needed priority to get it fixed.

Fedora Core 5 has managed to solve several problems from FC4 and others. In addition to providing several of the /dev entries :

from ls dev/ :
sequencer  
sequencer2  
snd         
snd/seq  snd/timer

the lsmod output also seems to make sense :
