Subject: ALSA: hda - Add prefer_hp_amp flag to hda_gen_spec
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ea46c3c87c35b90139b4dca43917d0f605d568ed;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Add prefer_hp_amp flag to hda_gen_spec

Add a new flag to indicate whether HP amp is turned on as default for
speaker or line-outs, and enable this for ALC260 codec, as many
machines with this codec require the HP amp even for speakers.
