I also have this model, and know this model has different number of PCM 
channels for its playback/capture. There's a lack of his explaination, 
but I can imagine that:

  * When the device plugging in, PulseAudio adds no sinks/sources for it.
  * So he judge a lack of the 'profile' is a cause of this issue.
  * Then he tries to apply custom profile for the device.

Certainly, PulseAudio 4.0 or former don't add sink/source for such 
devices. Furthermore, PulseAudio 6.0 has a bug to manage to apply the 
same profiles to both sink/source. (This bug was already fixed in 
current master.)

He loops to add a workaround for this issue to the former PulseAudio 
versions. Is it your aim of this message, Rene?
