On my machine speaker-test just plays some wav files in /usr/share/sounds/alsa, there's nothing magical. A change in hardware could make them announce the wrong speakers.
My latest eureka moment was from setting
/etc/asound.conf to
defaults.pcm.card 1
defaults.ctl.card 1
defaults.pcm.card 1
defaults.ctl.card 1
For using a USB sound card which is card 1. Very simple, now all my sound comes out there, $10 sound card.

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.
