Comment(by anonymous):

 I've just tried using the feature, by changing my alsa output device to
 the "ALSA:<usual-one>|surround51m" as mentioned above. I've created the
 surround51m device in my asound.conf, and confimed it works via aplay - it
 also looks to use the same routing as my normal one. I usually use one
 I've called softvol, which is a software scaling PCM slaved to fakerear,
 which is an upmixer slaved to sblive-audio.

 Anyhow, that makes my output device line: ALSA:softvol|surround51m - which
 results in no audio at all. With logging at important,general,audio - I
 get:
