The problem he is facing is that if you have, say, 3 RME HDSP's, the
information used to identify them to ALSA (at least) is identical in
every case. It is therefore tricky to ensure that what you consider to
be the "first" card is always hw:0 and so forth. The usual ALSA
mechanism relies on PCI id and other stuff that, IIRC, is not going to
distinguish between 3 identical cards.
He does *not* want to run the 3 cards as one, and if he does, he knows
he has to keep them in sync.
I don't know of a solution to this. I guess that the PCI registers for
the cards contain some kind of serial number, but how you can get ALSA
to based its snd_index assignments on that, I don't know.

Humm, that's a pretty glaring disappointment,
assuming it's true, and
I have no reason to believe it isn't. Hi,
I'm aware of and use standard Alsa methods to keep different sound
cards in the same system straight as far as Alsa is concerned. I'm
wondering what the proper process would be to keep 3 HDSP9652's which
are physically in the same system, or multiple USB sound devices
external to the system, straight as far as Alsa is concerned. I'd like
to know that a certain card always will be always be card 0, card 1 or
card 2. I do not want Alsa or Linux to make this decision for me and I
certainly don't want Alsa to change them from boot cycle to boot
cycle.
I needed to solve this problem a while back. The best help I got was
telling me it was not possible.
