[alsa-devel] [PATCH 085/112] ALSA: hda - Initialize output paths with current active states

[Takashi Iwai]

Set path->active flag at the path creation time and let the paths
initialized according to the current path->active state in
set_output_and_unmute().  This allows to modify the active flag of
some output paths dynamically, e.g. switching the front output route
with or without aamix like patch_via.c.
