hi all,

(posted the same message on the alsa-user list, but without reply, now trying 
here)

i have a machine with two pci devices of the same type. how can i ensure 
persistent device indices?

the wiki [1] mentions a way for a way using vid/pid, but for pci devices it 
suggests to write a udev rule. [2] 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)?

thanks, tim
