The voice for "Front Left" comes from "Front Left","Front Center","Rear 
Left", "Rear Right" and maybe "LFE" speakers.

The voice for "Front Right" comes from "Front Right","Front 
Center","Rear Left", "Rear Right" and maybe "LFE" speakers.

These are the only two voices I can hear at all. If I run instead:

~$ LC_ALL=C speaker-test -D surround51:CARD=SB,DEV=0 -c6 -twav

speaker-test 1.2.8

It happens the same: the voice for "Front Left" comes from "Front 
Left","Front Center","Rear Left", "Rear Right" and maybe "LFE" speakers.

The voice for "Front Right" comes from "Front Right","Front 
Center","Rear Left", "Rear Right" and maybe "LFE" speakers.

These are the only two voices I can hear at all. But strangely the order 
of the tested speakers this time it's changed.
