The first thing is that the problems with the 1212 should be looked at
separately. Also, there have been threads about pcm-multi on this list
before even with two "identical cards". Also, as far as I know, pcm-multi
and RT don't play well and even with a more relaxed kernel there are xruns
though they may not affect sound. Using alsa-in/out or zita-a2j and j2a
seem to have worked better in that case and may help in yours as well. Set
jack up as normal with the 1010 and add in the 1212 with alsa-in/out or
zita-a2j/j2a. (the zita package seems to use less CPU and is higher
quality... I am told, I haven't noticed one being bad) In this way it
should be easier to trouble shoot the 1212 problems because pcm-multi is
not involved and syncing is not involved either. So you should be able to
use the 1010 as a spdif input without interaction of the two kernel
drivers.

I'll think more... maybe look back in the LAU archives for other
pcm-multi/dual soundcard threads.
