Paul,
   This makes perfect sense, and it isn't what I did. (!!)

   The PlanetCCRMA has a Nano-HOWTO on how to install the MidiMan 2X2 by
hand. It's a little USB-based MIDI interface (not a sound card) that is
not recognized by alsaconf, so we do a bit of editing by hand.

   alsaconf sets up modules.conf for the HDSP

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 0.9.0 ---
alias char-major-116 snd
alias snd-card-0 snd-hdsp
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
options snd major=116 cards_limit=1 device_mode=0666
options snd-hdsp index=0
# --- END: Generated by ALSACONF, do not edit. ---


We then modify one line in the file to look like this:

options snd major=116 cards_limit=2 device_mode=0666


and we also do the following:

<SNIP from the Planet>
add usb-midi and audio to the /etc/hotplug/blacklist file
So that the OSS audio and usb-midi modules are not automatically loaded
when the device reconnects after the firmware download. Add ``usb-midi''
and ``audio'' in separate lines at the end of the list of blacklisted
modules in that file. 
<End SNIP>

I think, according to your info, that the problem is caused by not
having some sort of 

options snd-midiman index=1

line. That makes sense to me, except that I don't know what to put there
since there actually isn't a driver. The goal is to get the system to
make some devices in /dev/snd. This works fine on a cold boot, but fails
sometimes on a warm boot. (At least I think it does, since sometimes I
get pcmC1D0 when I have no pcmC0D0

Thanks,
Mark
