most likely it is the difference in he drives from XP to Vista.
best to ask the manufacturer of the audio device or the driver supplier.

my computer has a realtek alc 882 hd audio. i have speakers connected via
optical output - my speakers can decode dolby digital. i also have headphones
plugged into the headphone socket.
in windows xp if i wanted to be quiet i can turn the speakers off and hear
everything from the headphones. for films with dolby digital the sound would
be output by sp/dif and the speakers would decode - the headphones would be
silent while any dolby digital was playing. to get this working all i had to
do was enable digital output on the speakers settings for the drivers.
in vista i cant get sound to come from the headphones and speakers at the
same time. in vista i seem to have to 2 outputs to choose from - speaker and
digital output. if i set digital output then the speakers work and if playing
dolby digital stuff the dd light lights up on the speakers but the headphones
are silent. if i set speakers as the default the speakers go silent but the
how do i get it to work like xp did? clearly the hardware supports this
since it works fine in xp.
