(posted the same message on the alsa-user list, but without reply, now trying
i have a machine with two pci devices of the same type. how can i ensure
persistent device indices?
the wiki  mentions a way for a way using vid/pid, but for pci devices it
suggests to write a udev rule.  has an example, but it only describes how to
set up the device names in /dev/snd. but how do i bind a specific device to an
alsa device index (hw:X)?
