tracking down noise

[VTgreen81]

I'm using Cakewalk Home Studio 2004 XL a M-Audio Delta 1010, My Motherboard is Shuttle AN50r with nForce3 150 chipset, The CPU is AMD Athlon 64 3000+, and a ton of RAM and because I'm wondering about conflicts, the video card is GeForce FX5200.

When tracking or just playing through the system there's no noise, clean as a whistle, but on playback we're getting static or crackles. We're not clipping, not even close. It's not acting like a normal SNR problem, when the signal goes up the noise goes up too, but only on the recorded track not in the monitors during tracking. So it seems that the noise is related to the processing. Bit/sample rate are set at 24/96.

Could there be an IRQ conflict between the soundcard and videocard? I can't believe that the CPU's not fast enough.

Help Please .

I don't know CW HS but .... You may need to set your buffers a little higher and see if the helps eliminate the crackling noise.
You could check to see if the 1010 and the 5200 are sharing IRQ's. If so, Uninstall the 1010 drivers\software and move the card to a different PCI slot. Try each slot till you find that it is no longer sharing, or you may find that it will always end up sharing with something. It wouldn't be much of a big deal if it had to share with something like a modem or NIC card.
