MAudio 2496 and new motherboard

[Qualitymix]

I've had an issue that has become quite annoying. No amount of IRQ research or tweaking has been able to solve my issue.
I got a new computer, popped my trusty maudio 2496 soundcard in there, and jack launches fine.
However, there is a rather consistent xrun that happens about every 5-10 seconds. This makes it impossible to record using the card, and I'm forced to use my firewire connection on my mixing board, which can't reliably achieve as good of latency.

It's been a while since I've worked on the issue, but I'm posting here hopefully for some insight and suggestions.

My OS is Ubuntu Gnome with KXStudio. Lowlatency kernel, RT priorities/permissions, everything set up the way it's always suggested throughout the linux audio community, and the way I've set my rig up for years.
I'd deduced that it is an issue between my motherboard and the card. Anyone have any insight?
Thanks guys.

Power mangement, bluetooth, webcam, network manager, polling of dvd/cd
are some things to watch for. A shared irq on the pci slot could exist.
If there are multiple slots, try moving the card.

You could install top and htop, and watch the processes taking place.
htop lets you kill a process by an f-key.

Things you don't need can be uninstalled, removed from start-up status,
and a system service's status can be altered from automatic starting.

Pci Express slots probably require an adaptor.

Are their audible pops/clicks during playback?

I'll also clarify that this is an issue only with this card. My FireWire and built in sound cards work fine. I've tried all the different PCI slots, verified there are no irq conflicts, and tested different distributions.
I've used htop to no effect. No evidence of any possible suspects causing issues.
There is an audible (the usual sound) click during recording and playback.

You could get a barebones ubuntu linux like bodhi,
install only timemachine, and the jackd version 1 or 2, that is -not- on your system now.

Have you tried recording during a live dvd/cd session?

record a continuing tone with timemachine, staring at htop running,
you might see something.

Have you gone in your bios, and shut-down hardware
not essential to audio?

There are two hardware choices supplied by the kernel module snd_ice1712, have you tried both?

If you have another input source, like a motherboard chip, can you
test with that for input, with mAudio as output?
Assume you have qjackctl and other patchbays.

Post your .jackdrc file? Is the card tested in a windows?

firewire Periods/buffer should be 3, pci 2, easy to forget
switching amid such an eccentric situation. Did you take a pencil erasure
to clean the card connector traces?

I HATE when such a good card has troubles.
Worth replacing the computer, but there must be something...

google your motherboard with ubuntu, or cubase, a great game title, or other major keywords?
Cheers

if you have nvidia video, a pclinuxos live cd might help, nvidia 3d driver is default,
works fine for my olden computer...

Run "lspci -v" and look for shared IRQs. And/or anything else like that you can think of. If you haven't already. You probably have.

What kind of motherboard is it... brand, model, chipset?

If this is a half recent motherboard it must use a kind of PCI to PCIe bridge to be able to connect legacy PCI cards like the 2496 (no first hand experience but I remember somebody mentioning this in another thread). This could be where your perf issues come from.
In which case, it could be time for an upgrade...

I remember the very same thing. I think I have actually posted a troubleshooting page from a soundcard manufacturer mentioning possible bandwidth problems. Probably it happened on Ubuntu Studio forums a couple of years ago and I cannot find the page (I posted this with reference to that page... but I did not link the page... smart me). This seems interesting.

There is also a second generation 24/96, redesigned for cost reduction
by reducing chip count, and whatever other shortcuts the beancounters
pushed through. I think the pcb on the newer models is not blue,
like the original.
