From 8c0d9649babcf7379dc94cb148bbd2a6d8792984 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 28 Jan 2008 12:30:17 +0100 Subject: [PATCH] [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.
