If 150K/sec is non-trivial PCI bandwidth, I think you should probably
ask for a refund on your motherboard. From a power management point of
view I'd like to agree that offloading this from the CPU is a good
thing, but Lennart's right - most newly built machines don't hook these
up, and adding a control that influences CD volume on a small number of
machines and does nothing whatsoever on a larger number isn't a sensible
UI optimisation.
