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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
