Are you sure that those devices really work ?
"speaker-test --device <device> -c<channels> -F s32_le"
not working:
- surround21:CARD=FCA610,DEV=0
- surround41:CARD=FCA610,DEV=0
- surround50:CARD=FCA610,DEV=0
- surround51:CARD=FCA610,DEV=0
- surround71:CARD=FCA610,DEV=0
any number of channels <= 10:
- default:CARD=FCA610
- sysdefault:CARD=FCA610
- plughw:CARD=FCA610,DEV=0
10 channels only:
- front:CARD=FCA610,DEV=0
- surround40:CARD=FCA610,DEV=0
- dmix:CARD=FCA610,DEV=0
- iec958:CARD=FCA610,DEV=0
- hw:CARD=FCA610,DEV=0

was the only way to get mixing one channel into two others working.
On all devices listed with '10 channels only' a Pulseaudio-channel_map
with ten elements has to be created. The only way to create less channel
numbers seems to be module-remap-{sink|source}.
