"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
- surround71to50:CARD=FCA610,DEV=0

pcm.surround71to50 {
     slave.pcm {
	type hw
	card FCA610
	device 0
	channels 10
     }

     type route
     ttable {
	0.0 1	# 1: Front Left
	1.1 1	# 2: Front Right

	7.1 0.5	# 7: Side Right -> Front Right
	7.3 0.5	# 7: Side Right -> Rear  Right
     }
}

--------------------------- snap --------------------------

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}.
