There are two methods of Power Management ... ACPI and APM.
APM (Advanced Power Management) is the older method, and allows the user to manipulate the IRQ and I/O addresses in the Device Manager (to a certain degree). ACPI (Advanced Configuration and Power Interface) is the newer, more advanced method, and supports IRQ sharing among multiple devices ... but does not allow the user to manually change the IRQ and I/O settings.
This is why you were unsuccessful in switching your sound card to IRQ 5 ... with ACPI enabled, you can't. This has nothing to do with Administrative Privileges.
Having several devices sharing one IRQ in WinXP and Win2K is perfectly normal, and unless you have some kind of actual device conflict, there is usually no reason to manually change any of the IRQ's.
Having said that, there are a few other things you should know.
1.) Previously, in Win2K, some people still felt the need to change reinstall the operating system and change the settings to APM. Sometimes this was necessary, in order to resolve a conflict. But with WinXP, unless you have the Professional version, you can't do this. Home Edition does not support APM. And if you are running a multiprocessor system, WinXP Pro will not install APM either.
2.) Microsoft does not recommend installing APM unless your mainboard does not support ACPI. And in that case, it's possible that your mainboard is too old to run WinXP without problems in the first place. At the very least, you would need a BIOS upgrade.
