IO-APIC 16-fasteoi madifx
The madifx is my sound card. I have no idea what the fasteoi is though…(anyone ?)
I have have 3 PCIe slots, one of them and the cars doesn’t show up at all, the other 2
both have the result above.
The last time a had to deal with IRQ’s directly was when is was trying to install a
soundblaster in an 486… :-)

Is this your audio interface on irq 16? If so why is
it sharing an IRQ? Move it to a different slot maybe? If this is a PCI card and there is
only one slot, I would suggest a different motherboard with more PCI slots. My personal
experience with sharing IRQs has never been good even using rtirq to separate things out.
One thing to try is in BIOS there is sometimes a setting that tells bios to set irqs or
not. I have found setting it to not lets the kernel set it and the kernel does a better
job. Also, some bios have a part where you can fix a PCI card to a irq, that may help.
I am sure some will say that if rtirq doesn't help there is a bad driver... OK. The
thing to remember is that PCs are not built for low latency but high throughput. Most
people find that high throughput makes for a "snappy" user experience. Low
latency to most HW designers means 30ms.
