i still don't understand your question quite correctly.
do you mean open a multi-channel (5ch) pcm stream wihh the
configuration above?
if so, it's not too difficult for sb live (but not always easy for
other cards). it would look like:
pcm.my5ch {
type multi
slaves.a.pcm "front"
slaves.a.channels 2
slaves.b.pcm "rear"
slaves.b.channels 2
slaves.c.pcm "lfe"
slaves.c.channels 1
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
bindings.4.slave c
bindings.4.channel 0
}
