littleall, le pb, c´est que les pilotes de ton chipset dépendent de ta carte-mère : c´est bien précisé sur le site d´Intel :
http://www.intel.com/supppport/chipsets/audiodriver.htm
" Due to the variety of different AC’97 codecs that are available, Intel does not offer AC’97 reference audio drivers for public download. Please refer to the system or motherboard manufacturer for any driver downloads or updates. If you have an Intel motherboard, please refer to the motherboard support site to determine which audio component is used on your motherboard."
Dsl, c´est encore en Anglais mais c´est tout ce que j´ai trouvé...
