I built a computer and everything is working great for the most part. I am running into a problem that is very frustrating and I was wonder if someone could help me figure it out.

I built this PC to record music on and speed and storage and everything is right but if I try to record through USB with a USB device I get this horrible popping and clicking problem. I though it was the device so I plugged it into another computer and everything sounded excellent, so I have ruled out the device. I have updated all drivers on this machine (almost 100% sure, but I could be overlooking one) and have updated all the drivers for the device. Still no change. I started digging a little deeper and have found something that I think might be the problem but I am not sure. On my system information it says that IRQ 5,10, and 11 are all being shared but the status says ok. What these all have in common is that 5 & 10 share a Standard openHCD USB Host Controller and 11 shares a Enhanced PCI to Host USB Controller. Could it be possible that the noise is coming from a device sharing the same IRQ? I have an Asus A7N8X-X board with an AMD Barton 2500+. Is it possible to move these devices to another IRQ address? What is the standard address for USB? Any clarification on the sharing or any ideas where I can start to debug this problem would be great!

It's pretty doubtful that the noise would emanate from conflicting IRQ #'s. When that happens, there's normally a freezup in the PC's operation or a device may just stop working period. Moreover, if you check in the Device Manager you'd notice a yellow exclamation or question mark next to a device having the conflict.

Not sure if this helps u, but u can free up 1 or 2 irq's by disabling your COM ports (possible in BIOS).

Which O/S are you using?

Does the problem also happen with music played from a commercial media source, like an audio CD?

Did you try different USB ports?

Did you troubleshoot it by doing a clean boot?

I'm using XP and I have tried every USB Port. When playing music everything sounds great its only when the COmputer is recording from USB that I get a problem.

Delete:
In the Device manager there is no conflicts so I guess that eliminates that possibility. Would disabling the com port (since they arent in use) help free up system resources?

It might be that there are known problems with the acutal USB device you are using. You might want to try Googling using the specific device you are using and see if anything turns up.

Or, if you provide us with more specific information one of us might be able to unearth someone with a similar problem and solution...
