From 04b5efe5fa7f71c37b938053666fac317b67c636 Mon Sep 17 00:00:00 2001 From: Charles Chin Date: Thu, 4 Feb 2010 10:28:02 +0100 Subject: [PATCH] ALSA: hda - Fix docking output for IDT 92HD8xx codecs This patch fixes docking output support for IDT 92HD81/83/88 family codecs. Typically one of ports 0xE or 0xF is used for docking output, while only port 0xF is common on all the three codec families. We don't want the pin to select the analog mixer here.
