(channels = 2, ifnum = 2).
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
try speaker-test -D plughw:C400
