And furthermore, the ordering of the cards appears to be non-deterministic!! That is, in a machine with two sound cards, repeated reboots end up with different cards in the first slot! How can that be? Something is throwing dice to select the card??
I had this kind of problem with a M-Audio USB MIDI interface. This interface works only when it has been fed its firmware by the computer. So on the first boot, it was detected last, after the init scripts had a chance to upload the formware, whereas on subsequent reboots, the firmware was already there and the interface was detected before the PCI sound card.
That makes sense, of course.
I don't know what could have that effect on pci cards (I did not reboot too many times but it seemed random and certainly not repeatable)... -- Fernando
