ACPI vs Standard

[bull2118]

I just powered up my new build on a foxconn mobo and installed a SB AUdigy 2 my dad gave me like 5 years ago. I installed all the drivers etc... now I get popping and crackling on some audio, somtimes I get no audio, and sometimes it works fine (till the screen changes?)

The interference seems to by cyclical... pop scratch scratch pop scratch scratch...like a good polka. That, and now the line out doesnt seem to work on the mobo so I cant even set that as my default audio out.

One post on the internet said "hey, switch from ACPI to standard PC and the world is your oyster". The topic doesnt seem to have been discussed since 2002 but someone else said "if you go from ACPI to standard doom and gloom"

Im lost, please help.


Thanks!

2002 was back when a lot more people still used Win98, ME, 2000, when ACPI could be rather glitchy, there were no dual-core processors, message signaled interrupts, PCI Express, APIC on consumer hardware, advanced processor PM and throttling features didn't work all that well anyway, and a dozen other contemporary features. Today, if you disable ACPI on reasonably current hardware, you lose support for all kinds of good things. Linux lets you get some of them back through specific kernel parameters, but not necessarily with acceptable results if the BIOS isn't coded with legacy support for these features in mind.

IOW, your problem is not ACPI. Could be a poorly placed voltage regulator or MOSFET, inadequate filtering/decoupling along one or more PCI slots, graphics card that is emitting some crazy EMI, problematic chipset programming decisions via BIOS, flakey Audigy2 card, and a number of other contributors, but not ACPI.
