loaded boot camp with Vista - no sound

Hi I loaded bootcamp with vista on intell / 10.5 and there is no sound.

i can see the audio meter rising and failing with sound but there is no actual sound.

?????

any help would be appreciated.

cheers

HI,

resolved it.

i called applecare and they advised to switch into vista.
then insert Leopard installer dvd
then run dvd and click as if to install bootcamp

the applecare chap advised that what it is really doing is installing all the drivers etc.

i went through until boot camp was installed in vista and then hey presto sound and everything.

weird because i had previously loaded the same leopard/vista/bootcamp and no probs but went to vmware (too slow with dragon naturally speaking and so reverted back to bootcamp) and experienced no sound at all. i wonder if vmware played around with something.
