[PATCH] ALSA: hda - Fix multi-headphone handling for Realtek codecs

From: Takashi Iwai
Date: Mon Jan 10 2011 - 08:47:35 EST


When multiple headphone pins are defined without line-out pins, the
driver takes them as primary outputs. But it forgot to set line_out_type
to HP by assuming there is some rest of HP pins. This results in some
mis-handling of these pins for Realtek codec parser. It takes as if
these are pure line-out jacks.
