I set the original card to off, then tried to load:
[General]
auto-profiles = no
[Mapping headphone]
channel-map = aux1,aux2,left,right,aux5,aux6,aux7,aux8,aux9,aux10,aux11,aux12
device-strings = hw:%f
direction = output
priority = 2
[Mapping speaker]
channel-map = left,right,aux3,aux4,aux5,aux6,aux7,aux8,aux9,aux10,aux11,aux12
device-strings = hw:%f
direction = output
priority = 1
with `pactl load-module module-alsa-card name=test device_id=1
profile_set=rme-babyface-pro.conf` but getting:
Failure: Module initialization failed
and in syslog I get a tiny bit more info:
... [pulseaudio] module-alsa-card.c: Failed to find a working profile.
I already tried device-string surround40:%f and 4 channels given that `aplay
-L` has but still no dice:

Also tried the multichannel-input and -output with or without padding with aux
to get 12 channels and I got the same error. This is what `cat

I was able to load the default profile, which gives me the current stereo
behavior, so not otherwise useful. Any other ideas?
