PulseAudio doesn't work with ICE1712 cards (without some faffing around
with manual config files, anyway). You could use PulseAudio with JACK
indeed, however all the programs listed can talk to JACK natively, which
would be a better option. JACK works perfectly with the M2496.

In JACK you will end up with 10 hardware output ports, and you will be
able to individually route audio from whichever program to either the
analog outputs, s/pdif, or both at the same time.

There is no need to remove PulseAudio; you can set the profile for a
particular card to "Off" and it will not touch it at all.

There be dragons down that route, and nobody seriously uses OSS on Linux
anyway.

PulseAudio makes some assumptions about audio hardware that doesn't fit
the ICE1712, but then PulseAudio is irrelevant to programs like Hydrogen
and Ardour.
