 That doesn't work here:
 $ pactl unload-module <some index>
 $ pactl load-module module-jack-sink channels=2 channel_map=11,12
 Failure: Module initialization failed
 (my interface has only 12 output channels, but the even lower number
 don't work) 
Ah yes:
channel_map
    Channel map. A list of comma-separated channel names. Must have the same number of
channels as the channels argument.
"channel names".  So probably things like system:playback_17 and
system:playback_18 rather than just 17 and 18.
