From: Takashi Iwai Date: Mon, 27 Jun 2011 10:34:01 +0000 (+0200) Subject: ALSA: hda - Check hard-wired DACs at first for ALC662 & co X-Git-Tag: MMI-PSA29.97-13-9~18103^2~124^2~70 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3af9ee6b83c4c3f2577719e31e7d2af1ce996557;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git ALSA: hda - Check hard-wired DACs at first for ALC662 & co Some Realtek codecs have the output pins hardwired with certain DACs. These DACs have to be assigned at first and assign the rest for multi-DAC pins so that all DACs can be assigned properly. Without such an optimization, speaker outputs may be assigned to the same DAC as the headphone or others.
