Audigy2 cracks during disk access with CMSS enab

Question

Hi, I've got the problem with sound becoming cracky when I enable CMSS3D and the computers reads from my harddri'ves.
Without CMSS it is fine, there are no sound disortions at all.
I've tried disabling APIC (NOT ACPI!) in the BIOS (first installing the "ACPI (Advanced Configuration and Power Interface) PC" driver
I've also tried changing the PCI Latency Timer in the BIOS to 64 from 32 which which improved the situation but did not get rid of it.
The reason I at all bring this up is that I was hoping that the new driver released by Creative would fix this issue but it did not:
"Creative Sound Blaster Audigy2 and Audigy2 ZS Driver Update .84.55" released 2 May 05
The other drivers I have are the ones included on the install CD plus these from autoupdate:
Creative DVD-Audio Player version .00.60
Creative EAX Console version .00.54
Creative MediaSource DVD-Audio Player v.00.82
Creative SoundFont Bank Manager Web Update ver .00.2
Creative Speaker Settings version .00.56
Creative Surround Mixer version 3.00.57
Sound Blaster Audigy 2 and Audigy 2 ZS Driver Update released 29 Jul 04
The cracking gets worse when I update to the EAX4 drivers released by creative 29 Jul 04 (that is as opposed to running with only the drivers included on the install CD)
With the EAX4 drivers released 29 Jul 04 the CMSS3D v feature stopped working, only CMSS3D v2 worked. But when I now upgraded to the drivers released 2 May 05 both modes work again...
This is on a Windows 2000 Pro SP4 /w att updates as of 2005-05-20 installed
A Epox 8RDA3+ with BIOS 07/29/2004 (latest)
AMD Mobile 45w Barton 2500+ @ 200x,5mhz (Problem is the same if I run at stock speed also)
3x 52mb sticks of RAM (the problem is the with only one stick...)
ATI Radeon 9800 Pro 28mb
3com server NIC 3C980-TX (the two onboard mobo NIC's are disabled)
Audigy2 soundcard (onboard mobo sound is disabled)
2X Maxtor 20GB D740X FDB harddri'ves in RAID- (mirroring) via serial adapters to the onboard Silicon Image RAID controller
x Maxtor DiamondMax9 PATA 200GB harddri've
Nexxus NX3000 300w PSU (most silent PSU according to www.silentpcreview.com which is important to me..)
nVidia Nforce v5.0 drivers without nVidia SW IDE driver (they have given me too much trouble in the past..)
Silicon Image v.0.0.50 drivers
ATI Catalyst v5.5 drivers (the version without "Catalyst Control Center" that requires .NET)
This is a clean install of Win2K, I had the problem before the clean install also.
As I said I have no problem if I disable the CMSS, then all is well, my speakers are Cambridge Soundsworks DTT3500 5. via digital DIN cable.
All this is connected to an industrial Riello 6kW UPS to remove any concern of bad power, the system is properly grounded.
I do not have any strange BIOS settings, I do understand all BIOS settings and have them set to appropriate values.
My system is properly cooled, Alpha 8045 HSF for the CPU, Zalman ZM-80HP for the GFX card. Two Pabst input fans, then one output and one on the GFX card and one on the PSU.Message Edited by hanzzon on 05-20-2005 09:30 PM

Answer 1

Boot from an external system disk:
Format the external disk Mac OS Extended (journaled) running Disk Utility form the Recovery Partition.
(Boot then hold down Command and R simultaneously).
Install OS X onto that external disk.
Boot from that external disk (Boot then hold down Option).
Using the Finder drag as many folders as you can to the external disk.
As a last-ditch effort you can use recovery software to recover files the Finder will not copy.
