I'd have to wire up quite a bit of hardware for that. I also read:
All device driver modules support the following parameters:
[...]
channels
Audio channels (defaults to 2)
channel_map
Channel map. A list of comma-separated channel names. The
currently defined channel names are: left, right, mono, center,
front-left, front-right, front-center, rear-center, rear-left,
rear-right, lfe, subwoofer, front-left-of-center,
front-right-of-center, side-left, side-right, aux0, aux1 to
aux15, top-center, top-front-left, top-front-right,
top-front-center, top-rear-left, top-rear-right,
top-rear-center, (Default depends on the number of channels and
the driver)
Trying to secondguess one's way from around there, one could try options
channels=18 channel_map=aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7,aux8,aux9,aux10,aux11,aux12,aux13,aux14,aux15,left,right
and hope that this causes Pulseaudio to (essentially) skip over the
first 16 channels and associate left&right with the last two channels.
Frankly, Pulseaudio belongs to a group of applications where I find the
documentation (if you can even find it) really enfuriating because they
do some sloppy sort of "cleverness" and then put down a half-baked
equivalent of a dirty notepad that explains close to nothing except to
the person writing down the notes.
