Having looked at the datasheet I agree with you, this seems
surprising. However, if I run speaker-test and then toggle the mutes
of LOUT1 and LOUT2 one by one, they toggle the headphones and speakers
respectively.

Additionally, to hear output on each device I have to set the
following pin modes:

Headphones: LINE1 pin mode at node 0x14 must be set to line out
(quieter)/headphones (louder)
Speakers: HP-OUT pin mode at node 0x10 must be set to line
out/headphones (same volume)

This bears little relationship to the datasheet.
