--- Comment #6 from Christian Vogel <vogelchr at vogel.cx> ---
Same problem with a Behringer X18R mixer as a 18ch input/output device, this
workaround only works when running in 18ch mode. Operation mode is selectable
in the Windows/Linux/Mac/Android mixing application to be 2 or 18ch in/out.

By default line-level returns are on channels 17/18, so it makes sense to put
front-left/front-right there. So a routing of 16 "aux" channels, then
left/right is used.

My /usr/share/pulseaudio/alsa-mixer/profile-sets/behringer_xr18.conf:

: ;
: ; Behringer XR18: 18 inputs, 18 outputs when in 18ch mode
: ;
: ; left,right comes at the end, because in 18ch mode the last two
: ; channels are routed to/from aux-input which is most likely where
: ; you want to have your mp3 player input or jingles or ...
