well, i changed the soundcard down two slots, and this is what i got:

i should perhaps explain that i'm using an asus a7n8x-x m/b - it has an onboard ethernet adapter, and two usb ports ...
when i go into bios to try and assign soundcard to irq 10 or 11, it has the option - by each irq - to set it to either "Reserved" or "PCIDevice".
By default they are all set to "Pci Device". I changed irq 10 to "Reserved", but that didn't change the soundcard setting, and then my ethernet didn't work.
It doesn't really seem clear in the bios how to allocate an irq to a certain pci slot ...

no ... :(
but i found the dmesg command somewhere, and it gave me some very
interesting output regarding usb and irq#10 (look near the middle -
where it indents a bit and talks about an irq screaming that noone cares
- and very bottom here)(i am including ALL of the output in case you can
glean some other important info from it):
