I came across this website when looking for a way to get rid of unexplained popping in my audio. It claims that the culprit is ACPI and that the problem can be corrected by changing your irg settings as explained below. Is any one familiar with this?? I followed the instructions and the pc rebooted and reinstalled all drivers. It seems faster and the audio sounds clearer for some reason.
After you read this you can read more about this here www.musicxp.net or searching for the the article entitled, "ACPI Kills Audio Performance by www.steinberg.net

If you are an audio mod or just a sound guru please comment on this. I would to hear everyones opinions on this setup. Thanks - Aratech
Cubase SX - Optimizing XP and Windows 2000
Before trying the following, check your motherboard manual and the manufacturers details for your soundcard - Some soundcards don't recommend Standard PC.
ALSO, read the disclaimer (below)
If you're suffering from pops and clicks in your audio streams with no obvious explanation, then read on...
First look at the System Device Manager and check the IRQ's for all your devices. If they are the same (or many of them are) chances are ACPI is messing wid ya mind. If they're not, LEAVE WELL ALONE! Go no further.
Buying a PC with Windows 2000 or XP pre-installed will often mean that it's not optimally configured for music applications.
When Windows goes through its installation routine, by default, it sets itself up in ACPI (Advanced Configeration and Power Interface) mode.
This applies a variety of internal settings that can affect the performance of the machine when it's placed under the sort of strain that complex audio work can produce, in particular, an ACPI configured PC will generally route all IRQ assignments to just one IRQ, even if others are free!
Simply put, this'll mean that any hardware present on your machine - audio and graphics cards for example - may struggle for bandwidth across the PCI Buss on the motherboard (or, as someone in the film Full Metal Jacket quoted, It's "...like sucking a golfball through a hosepipe!").
When you start throwing complex GUI's and high-res screen redraws through the graphics card while still trying to shuffle 16 tracks of 24-bit/96khz audio around, these two processes can begin to steal resources and lead to graphics problems, audio glitching and popping - Cubase SX is particularly sensitive to this and it's likely that ACPI is the culprit!.
If this sounds sounds familiar, try this:
Open Control Panel
Go to Hardware Settings
Click the small '+' sign to the right of the computer entry
...if it says ACPI Advanced Uniprocessor PC - Chances are your audio and graphics card are sharing IRQ's...uh oh!
Windows XP users should
Right Click on ACPI
Select Update Drivers
Select from list
Select "Standard PC" (at the bottom)
Hit Apply.
Windows will now reboot and reinstall all of your hardware, assigning each item to an individual IRQ
Windows 2000 users, should not do it.
W2K doesn't like it and can't handle ACPI properly.
