From 29fa79cefe6faaf148bc936ed338c02f0bd582ec Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 30 Aug 2019 12:03:38 +0200 Subject: [PATCH] ALSA: hda/realtek - Fix overridden device-specific initialization commit 89781d0806c2c4f29072d3f00cb2dd4274aabc3d upstream. The recent change to shuffle the codec initialization procedure for Realtek via commit 607ca3bd220f ("ALSA: hda/realtek - EAPD turn on later") caused the silent output on some machines. This change was supposed to be safe, but it isn't actually; some devices have quirk setups to override the EAPD via COEF or BTL in the additional verb table, which is applied at the beginning of snd_hda_gen_init(). And this EAPD setup is again overridden in alc_auto_init_amp(). For recovering from the regression, tell snd_hda_gen_init() not to apply the verbs there by a new flag, then apply the verbs in alc_init().
