ad1848 isn't blocking the insmods properly. So it's not ready
for mad16 to be insmodded until afterward.

You could try that, but it may fail if you don't wait the proper
amount of time.

What I would do:

insmod up to and including mad16
until (echo >/dev/dsp); do rmmod mad16; insmod mad16 (mad16 parameters go 
here); done

This loops until something is successfully written to /dev/dsp.
This will not work if you need to wait a certain amount of time
between insmod attempts. You will need to add sleep if that is
the case.

No idea here. It may not be capable of doing that.

Absence of evidence is not evidence of absence. It may be rare
enough that no one has tried it with mad16 and reported.

MIDI files are a completely different kettle of fish. The SBPro
emulation may be suspect, as you suggest.

It is probably compatible. The Crystal chips do emulation of
various standard cards.
