I have to correct myself. That configuration is wrong. This
is more like what might actually work (with a hw mixing
sound card, that is):
# The first stereo pair:
load-module module-alsa-sink sink_name=speakers channels=2 channel_map=left,right
# The second stereo pair, the random aux channels shift the
# real channels to the next physical output:
load-module module-alsa-sink sink_name=headphones channels=4 channel_map=aux14,aux15,left,right
