[Raymond <1361434@xxxxxxxxxxxxxxxxxx>]

does notebook support 5.1 ext speakers since there are three jacks at
same location (ext front) and stac9228 is a 8 channels codec ?

do  headphone Jacks node 0x0a and 0x0f support surround 4.0 ?
 
do the driver assign correct name front/surround to the headphone jacks ?
