Some distros do the alsactl save as part of the shutdown
sequence(/etc/rc?.d/K*). If it doesn't then once you deleted asound.state, it
should not be recreated. Not until you run alsactl save. At least that's how
it works in debian. I know this because if asound.state exists, then it
doesn't restore the mixer settings that were set and saved in some other mixer
like aumix. YMMV
I still think you're missing the /dev/'s though. Or maybe you just need the
/etc/modprobe.d/ configuration. Multiple cards can be tricky. From what I've
gathered, most of your errors are cannot open device, or device does not exist.
If you can't get past that, they you probably wont be able to do anything with
that device.
I have different cards, but this is how I set mine up. Usb audio does require
usb support. And I've been configuring mine custom-ish for a while. There's
probably an alsaconf in the alsa-utils package that sets this stuff up for you.
But I never got it to work for me back in the day. So I almost always set
things up long hand. Fortunately with usb sticks, that's just a cp or cut and
paste away.

This is good enough to use the cards and have their drivers autoload when you
try to use them. If I want alsa native apps to use the non zero card, then I
mearly change the number on the defaults.pcm.card line. OSS type apps will
almost always default to 0, unless you use aoss. Not that much of an issue
since you can always change the index numbering to make whatever device be
device 0. The asoundrc defaults line is just a lot fewer lines to change, and
doesn't require restarting alsa. /etc/init.d/alsasound stop|start
Not that you have go the defaults route. Many existing apps let you specify
which card to use. By either it's hardware number or it's asoundrc label. $
mplayer -ao alsa:device=hw:0 (or device=atiixp). -D hw:0 for arecord. -d, or
-C or -P for jackd. And various gui preferences to help you utilize secondary
cards and friends.
