portable gigabyte P34W4 problème son

Bonjour,

Aprés des recherches sur le net sur le sujet, je reste sans solution concernant un soucis de son sur mon portable
modele: gigabyte P34W4
distribution: ubuntu 16.04
problème:Le son focntionne correctement sur un boot en windows, mais sous ubuntu 16.04 et version précédente (test en 12.04 et 14.04), le son fonctionne sur le port Jack mais pas sur les enceintes intégrées.

Un petit tour dans alsamixer me montre un transfert correct des volumes en branchant/debranchant le prise jack
Les sorties audios basculent correctement de 00 en MM
Un appui raccourcis fn+F7 (stop/start du son) donne un petit son scratch dans les enceintes mais pas plus.

j'ai consulté et appliqué les solutions proposées sur les liens:
https://doc.ubuntu-fr.org/son_problemes
https://doc.ubuntu-fr.org/audio_intel_hda
sans résultats.

Je donne les résultats de mes logs de commandes au cas ou certains seraient en mesure d'identifier mon problème....
En espérant que d'autres ont été confrontés à ce problème et qu'une solution existe.
Merci
