Amanda, This sounds like a PCI error of some sort, it appears to probe the PCI bus and and cannot find the card. The message shows it assigned an interrupt (IRQ 9) but then says cannot find the slot for index 0 (range 0-0), that could also be related to the ACPI which among other things dynamically assigns the interrupts. Maybe it is conflicting with the other sound card or another PCI device. A few things that you could check: If you do lspci command does it show both sound cards? Have you tried getting each sound card working separately before trying to get them both working at the same time? In the BIOS settings there is configuration for PCI slots, you may be able to do manual setting the PCI slots that have the cards installed rather choosing auto. Two other possible BIOS settings you could try are turning of the "PnP Aware OS" setting and turning off the ACPI setting. If you try these try them one at a time to see if they make any difference. It would be worthwhile to try to find out what the error code -12 means on the following error message EMU10K1X: probe of 0000:00:0f.0 failed with error -12 Perhaps looking at the alsaconf source code would help determine what triggers the -12 error and what it means, depends on if the code is well documented. BTW I love your email signature, continuing on with the Williamson quote ... There is nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine, as children do. We were born to make manifest the glory of God that is within us. It's not just in some of us; it's in everyone. And as we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others ... -- Doug
