Delta 44 pops and clicks

I finally bit the bullet and bought a Delta 44.

When I record at 24bit/44.1 the recording is generally ok, but when I record at 24bit/96 the recording ends up with a hell of a lot of pops and crackles.

I realise this could be caused by a number of things.

My system specs:

AMD Athlon XP 1700
MSI K7T266 Pro2 motherboard
512MB RAM
Leadtek Winfast GeForce3 TI-500
30GB Maxtor HDD
20BG IBM Desktar HDD
Windows XP (in ACPI mode)

I've checked my IRQ's and the soundcard is sharing IRQ16 with the graphics card.

Now of course first off I'm pretty annoyed that a card of this
expense ($AUD600) doesn't work as documented, but that aside, has anyone got any ideas (other than the following) to try?

I've tried the following things to get a remedy without success:

- Turned off graphics acceleration in XP
- Uninstalled the card, removed the drivers, reinstalled the card, to try and get it on a different IRQ
- Tried different M-Audio driver versions (.25 WDM, .27 and .31 beta)
- Disabled COM/Parallel/USB ports (to free up for IRQ change)
- Disabled on-board sound/modem on the motherboard

I'm in the process of doing a complete reinstall but I was just wondering if anyone else has had any trouble with the Delta 44 and what they did, if anything, to remedy it... or any suggestions more than welcome. Thanks guys and gals!!
 
You may need to adjust the buffer recording at 24/96
Also, go to your bios and force the card not to share an IRQ as sharing with a graphics card is a no-no
 
Try disabling ACPI. I understand this is best done when installing WinXP. You'll need to get some instructions on how to do this, as it's not intuitive. Try a google search. If you can't find anything, post back and I'll see if I can dig them up.

Another thing to try would be a BIOS update for the MOBO.

BTW, as an aside, personally I would continue to record at 44.1 unless you're planning to make DVD's. The downsampling back to 44.1 for CD's will negate any gains of recording at the higher sampling rate.
 
I had a similar problem and disabling ACPI worked for me. I still have to configure my system to work without ACPI but it got rid of the crackle. Oh yea, I'm using win2000 so this might not work in xp.
 
Doesn't WinXP install with ACPI off by default?
 
Aha! Now I see the bigger picture here. You omitted the fact that you have an AMD system with the KT266 chipset in your other post. I would venture to say that that could very well be the source of your problems. Deltas as well as other cards have been known not to get along with VIA chipsets sometimes...
