Sound issue!

[John Pierce]

Hello all, I have upgraded two computers in the last 3 days and one of
them has a really weird sound issue.  On the laptop everything has
sound, music (amarok), video (dragonplayer and xine), even the
notifications are working perfectly.  On the desktop system the
notifications works perfectly fine, but the output of music or video
files does not work.
This is the output of lspci from the affected computer:

This is the output of lsmod | grep snd

It is very strange that there is no output from the different
applications.  Any thoughts or suggestions would be greatly
appreciated.
