I did a search for "irq" on this website http://www.manualowl.com/m/Asus/P8Z68-DELUXE%2FGEN3/Manual/263040?page=91 and found a page (2-14) that lists the (non-alterable???) IRQ assignments for my motherboard. The good news is that one of the legacy PCI slots has less stuff on the IRQ. The bad news is that one of the PCI slots has lots of stuff on that IRQ. Looking at IRQ 16 above, my nVidia shows up. It's PCiE x16, and my motherboard seems to have 3 of those slots, with one slot being on a different IRQ. I suspect moving the video card might help, right? Basically, my strategy would be to disable drivers I don't use. For instance, I don't have any firewire gear. Next, I'd move anything I could to a slot using a different IRQ than the one I want to reserve for the Delta 1010. Seem like a good plan? Thanks! P.S.: I had this system custom built for audio work. If/when I get this working, I'll provide feedback to my system builder as to what works well. I'll also post my solution here. -- Kevin _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
