OK, thanks for the suggestions. Here they are:

For good measure I ran that one as a general user:
baz ~ $ pactl list sinks short
0 alsa_output.pci-0000_00_1f.3.analog-stereo module-alsa-card.c s16le 2ch44100Hz SUSPENDED
baz ~ $
(That ought to teach me about automatically running system commands as root)
lsmod was too long for the screen, so I tee’d it into a file and copied it from Emacs.
