Default two sound cards, keeping their HW number

OK, I've finally had a chance to see if this worked, and it didn't. The last
two times I rebooted, I had to switch QJackCtl by hand to the other card. I
just verified that my asoundrc stuff looks right:

# ALSA library configuration file managed by asoundconf(1).
# Manual changes to the ALSA library configuration should be implemented
# by editing the ~/.asoundrc file, not by editing this file.
!defaults.pcm.card Live
defaults.ctl.card Live
defaults.pcm.device 0

But this doesn't seem to have any effect on anything. QJackCtl still sees my
ice1712 as card 0 this time around (it was card 2 last time) so I've been
using my emu10k1 for playback all this time without realizing it. I have the
two cards synced through SPDIF, and all the audio ultimately comes out of the
ice1712. It doesn't seem to matter which card is which for day to day
playing around (probably says something about how my ears aren't very
sensitive), but the difference becomes critical at recording time.

That's the real bother here. I wanted to play with recording, and I noticed
the only signals in Envy24Control were coming from SPDIF IN. Then I expanded
the alsa_pcm entry in QJackCtl, and lo, I only had two inputs and two
outputs. Must be using the wrong card. AGAIN.

Unless there is a more sure recipe than this asoundconf thing (like being able
to force the hw:x order at every boot) I guess I have no remedy other than to
try to remember to look at QJackCtl each time and see which hw is which. (In
addition to these two, I have a USB MIDI dongle that takes a card slot, even
though it doesn't produce audio. That one always seems to come up card 1,
and it's just 0 and 2 that keep flipping randomly.)

Or maybe I'm just stupid, and somebody needs to take a deep breath and start
at page 1. Or better yet, suggest a way to hack this stupid thing so that I
always know which is card 0, and which is card 2.

(And hey, on the bright side, now that I have shut everything down, changed
QJackCtl, and started it all back up, I have got my old mAudio AudioBuddy
working backwards as a headphone amp monitoring the analog outs on my
Audiophile 2496, and so I finally have the ability to monitor something other
than my Sound Canvas on headphones. This is something I haven't been able to
do since my old amp blew up; the one that had a handy headphone jack on it.
So now I can do live audio recordings over top of other live audio recordings
like hasn't been possible in years. Joy!)
