From 4386363312d70a764a376f1635467bab8e26965a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 20 Sep 2012 07:44:11 +0200 Subject: ALSA: hda - Workaround for silent output on VAIO Z with ALC889 commit e427c2375646789ecd0ccaef1a1e41458559ab2d upstream. On recent kernels, Realtek codec parser tries to optimize the routing aggressively and take the headphone output as primary at first. This caused a regression on VAIO Z with ALC889, the silent output from the speaker. The problem seems that the speaker pin must be connected to the first DAC (0x02) on this machine by some reason although the codec itself advertises the flexible routing with any DACs. This patch adds a fix-up for choosing the speaker pin as the primary so that the right DAC is assigned on this device.
