Does it handle "Independent HP" ?

VIA codecs
----------

* 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.  In the case the headphone DAC is shared with a
  side or a CLFE-channel DAC, the DAC is switched to the headphone
  automatically.

Analog codecs
--------------

* 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.
