Ok, hibernate and standby both work fine now-now that i am using an add in graphics card (go figure?). Things aren't perfect though, because now when I come back from standby, the optical link on the sound card aparantly doesn't turn back on. But if I shutdown, then power back up, it comes up ok and you can hear music through it. (I run toslink from sound card to digital audio processor in car).
Have any of you who use toslink in your cars run into the toslink on a computer not "powering" back up (little red light is OFF) after a standby/hibernate?
