Neither am I!  Ditto with the issues.  There are experts around.

You're asking the wrong guy!  I just use the page I pointed you to, web
search, and trial and error to get an .asoundrc that works.  I don't
actually use one right now.

I notice that your USB device is actually interpreted as 4 cards.  Are
they each of different functionality?  You could try (as a wild guess):

 pcm.drecord {
     type dsnoop
     ipc_key 1025
     slave.pcm hw:audiodevice0
 }

All this is supposition on my part.  Maybe it will give you enough of a
hint in some way to get it working.
