Anyone have any ideas about the following? As a side note, when I saw
raw I don't mean 61937 raw (just preambles and payload), I mean 60958
raw (block sync, payload, VUCP).

I haven't got a lot of help for you as I'm not knowledgeable about this
but I can give you some suggestions.
You could ask you question on alsa-devel mailing list as they know the
internals and might be able to answer your question directly.
You could look at the alsa driver code. Go to
ftp://ftp.alsa-project.org/pub/driver/ and download
This is the latest official alsa version. Unpack it and then look in
"top level"/alsa-kernel/pci/emu10k1. That has the C source.
