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:
