> I´ve had the same problem and in my case it was the driver of the soundcard
> Vista installs its own driver which basically works fine, but by default the
> channel(s) for CD audio and DvD sound are set to disabled or mute
> I´ve been searching in the sound settings of the Vista driver, but couldn´t

> In my case I found a fitting driver for the soundcard at the Realtek

> enable the missing channels
