I wrote that speaker-test program.
It tests ALSA.
ALSA has a fixed channel ordering so that all applications can use the
same order.
If the speaker-test program is getting the order wrong, then the
problem is one of:
1) Speaker wires connected wrongly.
2) ALSA driver bug.

Another test to try is:
speaker-test -twav -c6 -Dplug:surround51

If speaker-test gets the order right, the bug is with the application.
If speaker-test gets the order wrong, the bug is with ALSA.
