Nate,

Does the sound work properly on the R32 and T23 after S3 resume? I
suspect the problem with my system is limited to very few models, maybe
just the T30 and R40. It only shows up in that sound plays too fast (at
the raw device rate rather then the programmed rate).

I do suspect that this is a PCI power issue and not an ACPI issue, but
I'd like to know if it shows up on more models. It is most obvious when
playing a stream as the buffers keep emptying and the sound stops after
a short time. Music is clearly too fast and high pitched, but at 10%
overspeed, some may not notice. (Does Dr. Dre sound much different 10%
faster?)
