speaker-test plughw:C400 got me further but complains still
Setting of hwparams failed: Invalid argument
From the manual:
2 analog mono inputs, 1 stereo SPDIF gives a total 4 inputs 4 analog mono outputs, 1 stereo SPDIF gives a total 6 outputs
Does SPDIF factor into channels?
I noticed, the endpoint attributes are slightly different that the FTU. Could this be an issue? I'm also guessing that the mixer lacking channels is probably an issue. I wonder if the some the FTU mixer "workarounds" may fit.

Why do you use channels=2. As fas as I can tell the device has 6 channels. Try that.
Except I can't get it to play anything (figure it would all be too good to be true)
$ speaker-test -Dfront:C400 speaker-test 1.0.25
Playback device is front:C400 Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Sample format not available for playback: Invalid argument Setting of hwparams failed: Invalid argument
The device probably supports only S24_3LE audio. At least that's what you tell Alsa with the FTU quirk. Try to play something through the corresponding hw device or use Jack or convert some audio file to S24_3LE and play through aplay etc...
that's a good point
