IRQ conflict in WinXP

[misle]

System:
1.4 GHz Athlon
Abit KT7A-Raid
512 MB Ram
GF4 Ti4200
SB Audigy OEM

I do a lot of recording and playback thru my Audigy. I have skipping and occasionally crackling when doing playback. It seems to be an IRQ conflict between my Audigy (IRQ 5) and the only other thing I found assigned to IRQ 5 is the USB. I have nothing plugged in to my USB ports. Occasionally I use my USB Zip drive, but that's it.

I know it probably has more to do with Creative's crappy drivers, but anyone have a recommendation on how to fix this. Possibly isolate the Audigy with its own IRQ?

Thanks,
-Matt

Disable your USB in the BIOS

Audigy is meant to be significantly better than Live, so it in itself shouldn't be the problem. I would suggest:

1. BIOS, change 'PnP OS installed' to DISABLED, apparently WinXP like tyo do things itself, also try ENABLING 'Reset the PnP Data' and finally ensure USB and VGA/AGP are assigned IRQs, as mentioned try disabling USB just to see if that fixes it, that would tell you your Aud doesn't like sharing the IRQ.

2. PCI cards, try swapping them around to different slots, but never put one next to the AGP card as this always gives headaches.

3. If you use a VIA mobo (KTxxx) then be sure to use the latest drivers and install the 'PCI Latency Patch', even if this doesn't help you it will do no harm and make your PCI bus much more efficient.

4. Play around with the Resource assigns in Device Manager and see if you can find a way to get Aud its own unshared IRQ and DMA settings, I had to do this when my old SB PCI128 didn't like my Epson SC640 and I gave the SB (Creative again) its own IRQs.

5. Take a sledge hammer (the tool, not the CPU) and smash that Audigy in to pieces ... damn Creative, damn them LOL!

I have a similar problem with my Soyo P4I fire Dragon and my audigy. I get sound clipping and occassional system locks. Creative told me not to share IRQ5 but everyone else says it's Okay. I think Creative needs to get off the pot and release better drivers that fix the problem.

You can't change the IRQ in XP so don't bother trying. It has to be done in the Bios under PNP/Periferals with a few PCI slot changes. Creative says the audigy "prefers" PCI slot 5. Disabling the USB is not a fix...... I've tried that. Besides, it means you can't use USB for anything so that is not a valid solution.

Nobody seems to be able to figure this out except so say that creative is problem. I have to agree. Live with it until the next patch comes out or RMA the card and try a different manufacturer.
