From 1cd9b2f78bf29d5282e02b32f9b3ecebc5842a7c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 2 Dec 2013 13:19:45 +0100 Subject: [PATCH] ALSA: hda - Fix bad EAPD setup for HP machines with AD1984A It seems that EAPD on NID 0x16 is the only control over all outputs on HP machines with AD1984A while turning EAPD on NID 0x12 breaks the output. Thus we need to avoid fiddling EAPD on NID. As a quick workaround, just set own_eapd_ctrl flag for the wrong EAPD, then implement finer EAPD controls.
