NEO-FIS2R PCI Slot IRQ Information

Question

I've got a NEO-F1S2R on the way and am trying to figure out where I should place my M-Audio Audiophile 2496 and Hauppauge PVR250 for optimum performance. In the past I found that I had to place my soundcard on PCI slot with its own IRQ, same with the PVR250, to get the best results (if not I found I got pops and crackles during audio playback).
Can anyone tell me how IRQs are assigned to each of the PCI slots? Which slot is shared with the AGP slot. Which slot(s) are shared with the RAID controller? I've searched high and low but can't find this information.
Any help is greatly appreciated.
Thanks,

Answer 1

you definatly want your own irq for the m-audio/midiman card, in my case i have my hammerfall card running in slot 3 (2 away from agp) and my uad card in slot 4 and both have there own irq without having to assign in bios, this might not be your issue though as maudio cards are very shoot and miss, althought it might cost 2-3 times as much as your soundblaster card, it is on the entry level tier of pro audio cards, having this said and done, they do sound great if they get working properly,
if you continue having problems after you solve your irq issues hit me a pm, as i am very experienced with recording systems of most platform, first thing i can tell you is if your using cubase sx or nuendo, make sure you select asio drivers for your midiman card,  apologies if youve already been this far, but that is the most overlooked part of a vst system, (if asio is a selection in your app be it sonar or acid ect pick asio over andy dx or mme drivers as they are the most low latency and high performing for windows pro audio solutions) other than that check your buffer setting from your apps, 1024 buffers is most recomended and will give you about 23 milliseconds of latency, smaller buffers will will reduce your latency but will require more juice from your system ect, again aplogies if you already know this,
