Iogear firewire 800 card sharing IRQ that I can't change

[Delmar Penner]

I tried a different PCI slot (3 different ones) and on two of those it used IRQ 16 and one of them IRQ 19. But both of those IRQs are being used by other devices.
The problem I have is that I have a fireface 800 (ff800) that I'm trying play my sessions through, and it is very clicking and crackling audio that I get. When using Adobe audition to record over dubbing, then it won't play at all.
I read different forums and they kinda lean very much toward not sharing IRQ settings for using the ff800.
Is there a way to change the IRQ other then changing PCI slots?

Windows XP Pro SP2
PCI WinTV Card
PCI delta1010lt sound card
PCI Iogear firewire 800 card (GIC3800W1)
AVG nvidia video card FX5200
1GB Ram
2.4ghz processor
480GB harddrive (80+400)

Any help very much appreciated

Hi everybody,
I was able to get this unit to be alone on an IRQ. Here's what I had to do:
I noticed that most of my PCI cards shared the IRQ. My delta 1010lt sound
card shared it with the onboard sound. I disabled the onboard sound device,
and then switched the Firewire card with the delta 1010lt. Now the firewire
card had it's own IRQ. This has completely taken care of the clicking and
crackling audio that I heard on every play back.
Hope this can be useful
