Problème alsa avec nforce audio

Bon, là j'ai une asus azn8x-x, audio intégré.
Le son fonctionne sous kde mais n'est pas opérationnel à 100/100. Je m'explique;
Impossible de faire fonctionner par alsa, seul l'oss fonctionne [oss simple et threaded), je n'ai pas de son avec xmms mais noatun et xine fonctionne.
Là ou cela devient problématique c'est lorsque je veux jouer à doom3, unreal quake4...
Quake3 : le son fonctionne depuis que j'ai installé les drivers proprios
Unreal tournament 2004: le son fonctionne que si je sui sen openal, mode low quality et sans mode software, de plus j'ai un grésillement strident et constant.
Quake4 et Doom3, que dalle, il dit qu'il ne détecte aucun périph sonore.

Si je fait un /sbin/discover, ca me donne : i810_audio
Un lsmod me donne ça :

Quand je fait un alsamixergui, il me met ça: funcion snd_ctl_open failed for default: no such device

Quand je fait alsactl store, il me dit :alsactl: save_state:1194: No soundcards found...

J'ai bien tenté avec modconf de virer le driver intel du son mais il réapparait à chaque redémarrage.

J'aussi modifié le fichier modules.conf ds /etc afin de définir un unique périf audio utilisant nvaudio mais toujours pareil, de plus il me le remet par défaut après un redémarrage
!

Other distributions

If the distribution you are using provides a configuration mechanism for audio drivers, use it to select the nvsound driver module for use with the nForce audio device. Otherwise, manually edit the module configuration file.

If your configuration file already contains an entry for the i810_audio or snd-intel8x0 drivers (open-source audio drivers that supports the nForce audio controller), that entry needs to be commented out with a # or removed:

# alias sound-slot-0 i810_audio

Add the following lines to the configuration file:

alias sound-slot-0 nvsound
alias snd-intel8x0 off
alias i810_audio off


Voilà c'est un peut gros mais je préfèrais en mettre le plus possible afin de comprendre ma situation actuelle.

Merci d'avance pour votre colaboration :) !!!
