No, no, it's not what I meant.  I already *reviewed* and replied your
patch.

I copy my previous reply once again.  Please read and test it.

===

Unfortuantely, moving this doesn't suffice.  There is the hibernation
resume that needs the explicit initialization again.

Also, calling this in alc_alloc_spec() isn't intuitive.  Although it'd
become a larger patch, I prefer making it more explicit, e.g. creating
alc_pre_init() function handling the pre-init procedure and call it
from appropriate places.

So I can imagine a patch like below.  Does it work for you?


thanks,

Takashi

Re: FW: move eapd coef function before ACT_PRE_PROBE state

[Kailang]

Hi Takashi,

The patch was work for me.
Thanks.

BR,
Kailang

OK, I'm going to apply the patch below.

From: Takashi Iwai <tiwai@suse.de>
Subject: [PATCH] ALSA: hda/realtek - Avoid superfluous COEF EAPD setups

Realtek codec driver applied the COEF setups to change the EAPD
control to the default mode (i.e. control by EPAD verbs) at the init
callback.  It works, but this is too excessive at the same time, since
it's called at each runtime PM resume.  That is, the initialization
should be done only once after the probe.  One may think that moving
this to the probe should be OK, but no -- there is a catch; when a
system resumes from S4 (hibernation), we need to re-initialize this
again manually, because it's out of regcache restoration.

This patch addresses the issue by introducing alc_pre_init() function
that performs such a task.  This is called from each codec probe
function, and it's called from the resume callback conditionally only
from S4 resume.
