The ICH audio loses it's speed sync and runs at its raw speed, which is about 10% faster than the "proper" speed of 48,000. I have had this problem with ACPI since suspend first started to work. I suspect that it's really a PCI power issue since it worked for a couple of days after Warner applied the PCI Power patches to V5. Unfortunately, these patches broke many systems and were backed out. Small parts were then merged, but the sound never would re-sync again. I'm still hoping that Warner can find the problem some day, especially now that V5 is stable. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
