Thanks for the help!
Now both my ~/.asoundrc and /etc/asound.conf look like follows:
-----------------
pcm.multi {
type plug
slave.pcm {
type multi
slaves.a {
pcm "hw:0"
channels 2
}
slaves.b {
pcm "hw:1"
channels 2
}
slaves.c {
pcm "hw:2"
channels 2
}
bindings [
{ slave a channel 0 }
{ slave a channel 1 }
{ slave b channel 0 }
{ slave b channel 1 }
{ slave c channel 0 }
{ slave c channel 1 }
]
}
}

This is what I get in the messages window of qjackctl:
/usr/bin/jackstart -R -dalsa -dmulti -r47040 -p64 -n5 -S -i2 -o2

It seems like Jack does not recognize the new "multi" device?
