[ALSA] hda-codec - Add SPDIF output support to AD1986a laptop-eapd model
The SPDIF output on AD1986A laptop-eapd model is disabled although some Samsung laptops have SPDIF output. Enable it after checking the pin default config. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
