* Independent HP
  When this enum control is enabled, the headphone output is routed
  from an individual stream (the third PCM such as hw:0,2) instead of
  the primary stream.

you need to turn on "Independent HP" before pulseaudio probe the alt analog
device since it is disabled by default

you need to add new mapping 


https://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/profile-sets/default.conf


[Mapping alt-analog-stereo]
device-strings = hw:%f,2
channel-map = left,right
paths-output = analog-output-headphones
paths-input = analog-input-front-mic
priority = 10
