Probleme de son toshiba p100

Bonjour,
je vient tout juste d'installer windows XP et je suis depuis une semaine en train d'installer tous les pilotes nécessaire au bon fonctionnement de mon ordi.
Apres maintes et maintes efforts et visites sur les forums je n'arrive pas a mettre le son. Je ne suis pas un génie de l'informatique non plus, chose qui n'aide pas. L'ordi me dit aussi que le PCI device n'a pas de drivers. j'ai essayé de telecharger des pilotes de partout mais incompatible,ca veut pas
est ce que quelqu'un pourrait m'aider?
voici la description de mon ordi

toshiba satellite p100-461 PSPADE-01E00XFR

et le rapport everest
