Subject: [PATCH 5.2 04/37] ALSA: hda/realtek - Fix overridden device-specific initialization
Date: Fri, 13 Sep 2019 14:07:09 +0100
Message-ID: <20190913130511.843613979@linuxfoundation.org> (raw)
In-Reply-To: <20190913130510.727515099@linuxfoundation.org>

From: Takashi Iwai <tiwai@suse.de>

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().
