intrepid sound issues

[JAY HOPPA]

I am running Unbuntu 8.10 which I used to be able to hear sound.  I now have no sound, line-in, or line-out. and also no headphone sound. Sound is not-muted, volume is up. it recognizes my sound card and it used to work.i have looked over past posts and do not know what to do. Any  other info needed?
