I have tested the patch. In 8ch mode, it works without any overrides
in the sense that the side channels go to the blue jack if I choose
8ch mode. In the 6ch mode, the line input also works (tested by using
headphones as a very bad microphone-like source).

Here is alsa-info in the 6ch mode:


And in 8ch mode:


Pulseaudio is not smart enough to decide by itself that it can toggle
the control and add 7.1 profiles. If I toggle the control manually and
restart pulseaudio, they appear.

If the role of the "Line jack" control is still unclear, just say so
and tell me what to do to figure it out.
