[newbie] Still No Sound

[David]

Hi
ive installed Mandrake 7.1 on an IBM P3 550mhz desktop 
after the install mandrake failed to see the sound crystal chip, i then
downloaded the Alsa rpm files on the mandrake website and the new hardrake rpms
too. howerver there is still no sound :-(( ive chatted to people who have sound
chips , rather than cards, and they have sound on their PCs so I must be doing
something wrong.... but what ???
