Hi Takashi,
Issue 1: The noise keeps occurring via speaker when Headset is plugged in. Issue 2: The humming noise is occuring when switching to sound of settings. The noise will be stopped when switching to other options of settings. Issue 3: The popping noise occurred for one second when plugged in and removed the headset.
This patch will solve this three issues.

Hi,
could you explain, why the power-save function causes this behaviour? Can we do something else than turning off the power-save codec settings to avoid such noises? I have this question because it's really easy to disable something, but I feel that the culprit of the noises might be just the wrong codec settings. I guess that you have probably full documentation for the codec and probably for the hardware, so it might be nice to find the real culprit.
Thank you, Jaroslav

Note that power_save_node=0 doesn't mean that the whole power saving is disabled. It disables the fine-grained power saving, i.e. powering down the unused widget nodes.
If so, I wonder whether this might be about the default pin-shutup behavior. I improved the click noise problem on my Dell desktop by disabling the pin shutup. See commit c0ca5eced222. Kailang, Hui, did you try to add the chain to ALC269_FIXUP_NO_SHUTUP?

This noise was not happen on poweroff. AIO use external AMP. So, it will be need to have a reference voltage via codec. So, Pin-ctls was not be 0. I apply option spec->gen.suppress_auto_mute = 1 to avoid that. Internal SPK PIN also don't enter to D3. But I find it just only happen on ALC274 family codecs. ALC274 pin enter to D3. Pin-ctls also be 0. So, power_save_node=0 will let PIN to D0.
power_save = 0 it also could solve issue.

Yes, avoid setting pinctl is only part fix, the ODM said the main problem is the EAPD pin is high->low->high->low periodically, it has sth to do with the widget node power state.

Got it, but does it prevent Nodes or the whole codec from entering D3?
Here the EADP is low, it is not because the set_eapd() is called, I checked the EAPD of all nodes, they are all 0x2 all the time. And patch_realtek already set the own_eapd_ctl=1, and the NID for speaker is 0x16, it is not in the:
static hda_nid_t pins[] = { 0x0f, 0x10, 0x14, 0x15, 0x17, 0 };
So the driver will not set the eapd to 0 for speaker. If keep_eapd_on=1 can prevent codec/nodes from entering D3, maybe it will help.

Actually it's possible to prevent the specific route (path) from the dynamic power down, too. You can look for the path and set path->pin_fixed=1. But it'd be a bit too tricky and complex.

I described the EAPD usage. It just need to set NID 0x14 to eapd on. 0x15 0x17 also could let EAPD on. (0x0f and 0x10 was support by very old codec ALC260) If it need to turn on eapd to enable external AMP or speaker, it only could setup one NID to turn on EAPD.

Hi Hui,
AIO was wire power cable. It doesn't include battery. I think AIO can use power_save = 0 option. Because codec power consumption was lower. It was 0.01W~0.02W without work time. How did you think?
CPU or VGA chip which power consumption was more than 20W above.

That sounds good. But I just checked the kconfig of ubuntu bionic kernel (4.15) , we set CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0 already. I guess there is some package to change it to 1, in the past it was TLP package.
Is it possible the HW has some problem. The EAPD is the output pin from codec, if there is no pull-up resistor for this pin and the codec is entering D3, what the status is for EAPD pin? high or low? After the codec is entering D3, is the EAPD pin open-drain output?
Thanks,

I guess that you have probably full documentation for the codec and probably for the hardware, so it might be nice to find the real culprit.
Note that power_save_node=0 doesn't mean that the whole power saving is disabled. It disables the fine-grained power saving, i.e. powering down the unused widget nodes.
If so, I wonder whether this might be about the default pin-shutup behavior. I improved the click noise problem on my Dell desktop by disabling the pin shutup. See commit c0ca5eced222. Kailang, Hui, did you try to add the chain to ALC269_FIXUP_NO_SHUTUP?
This noise was not happen on poweroff. AIO use external AMP. So, it will be need to have a reference voltage via
codec.
So, Pin-ctls was not be 0. I apply option spec->gen.suppress_auto_mute = 1
to avoid that.
Internal SPK PIN also don't enter to D3. But I find it just only happen on
ALC274 family codecs.
ALC274 pin enter to D3. Pin-ctls also be 0. So, power_save_node=0 will let
PIN to D0.
power_save = 0 it also could solve issue.
Yes, avoid setting pinctl is only part fix, the ODM said the main problem is the EAPD pin is high->low->high->low periodically, it has sth to do with the widget node power state.
FWIW, there is also spec->gen.keep_eapd_on=1 that prevents the EAPD toggle at power saving.
Got it, but does it prevent Nodes or the whole codec from entering D3?
Here the EADP is low, it is not because the set_eapd() is called, I checked the EAPD of all nodes, they are all 0x2 all the time. And patch_realtek already set the own_eapd_ctl=1, and the NID for speaker is 0x16, it is not in the:
static hda_nid_t pins[] = { 0x0f, 0x10, 0x14, 0x15, 0x17, 0 };
So the driver will not set the eapd to 0 for speaker. If keep_eapd_on=1 can prevent codec/nodes from entering D3, maybe it will help.
Thanks,
Hui.

Is it possible the HW has some problem. The EAPD is the output pin from codec, if there is no pull-up resistor for this pin and the codec is entering D3, what the status is for EAPD pin? high or low? After the codec is entering D3, is the EAPD pin open-drain output?
Well, it'd be helpful if you guys clarify more specifically what we need to disable. Is it only about EAPD pin for NID 0x14? Or anything else? Depending on the requirement, we may have another less intrusive fix.

Hi Takashi,
I attach new final patch.
Fixed Dell AIO speaker noise. spec->gen.auto_mute_via_amp = 1, this option was solved speaker white noise at boot. AIO with external AMP, pin output doesn't fill 0x0.
codec->power_save_node = 0, this option was solved speaker pop noise at resume back.
I think add upper two options was needed. Many Thanks.

FWIW, there is also spec->gen.keep_eapd_on=1 that prevents the EAPD toggle at power saving.
Got it, but does it prevent Nodes or the whole codec from entering D3?
Here the EADP is low, it is not because the set_eapd() is called, I checked the EAPD of all nodes, they are all 0x2 all the time. And patch_realtek already set the own_eapd_ctl=1, and the NID for speaker is
0x16, it is not in the:
static hda_nid_t pins[] = { 0x0f, 0x10, 0x14, 0x15, 0x17, 0 };
So the driver will not set the eapd to 0 for speaker. If keep_eapd_on=1 can prevent codec/nodes from entering D3, maybe it will
help.

Hi Takashi,

This patch will solve this three issues.
Hi,
could you explain, why the power-save function causes this behaviour? Can we do something else than turning off the power-save codec settings to avoid such noises? I have this question because it's really
easy to disable something, but I feel that the culprit of the noises might be just the wrong codec settings. I guess that you have probably full documentation for the codec and probably for the hardware, so it might be nice to find the real culprit.
Note that power_save_node=0 doesn't mean that the whole power saving is disabled. It disables the fine-grained power saving, i.e. powering down the unused widget nodes.
If so, I wonder whether this might be about the default pin-shutup behavior. I improved the click noise problem on my Dell desktop by disabling the pin shutup. See commit c0ca5eced222. Kailang, Hui, did you try to add the chain to ALC269_FIXUP_NO_SHUTUP?
This noise was not happen on poweroff.
The pin shutup change helped at the resume click noise in my case.
AIO use external AMP. So, it will be need to have a reference voltage via codec. So, Pin-ctls was not be 0. I apply option spec->gen.suppress_auto_mute = 1 to avoid that.
If a specific widget must not enter D3, you can filter out by setting with power filter. An example is found in patch_sigmatel.c stac_vref_led_power_filter() which avoids D3 on AFG node for keeping mute LED working.

Internal SPK PIN also don't enter to D3. But I find it just only happen on ALC274 family codecs. ALC274 pin enter to D3. Pin-ctls also be 0. So, power_save_node=0 will let PIN to D0.
power_save = 0 it also could solve issue.
thanks,
Takashi

Hi Takashi,
Issue 1: The noise keeps occurring via speaker when Headset is plugged
in.
Issue 2: The humming noise is occuring when switching to sound of
settings.
The noise will be stopped when switching to other options ofsettings.
Issue 3: The popping noise occurred for one second when plugged in and
removed the headset.
This patch will solve this three issues.
Hi,
could you explain, why the power-save function causes this behaviour? Can we do something else than turning off the power-save codec settings to avoid such noises? I have this question because it's really
easy to disable something, but I feel that the culprit of the noises might be just the wrong codec settings. I guess that you have probably full documentation for the codec and probably for the hardware, so it might be nice to find the real culprit.
Note that power_save_node=0 doesn't mean that the whole power saving is disabled. It disables the fine-grained power saving, i.e. powering down the unused widget nodes.
If so, I wonder whether this might be about the default pin-shutup behavior. I improved the click noise problem on my Dell desktop by disabling the pin shutup. See commit c0ca5eced222. Kailang, Hui, did you try to add the chain to ALC269_FIXUP_NO_SHUTUP?

Only ALC274 has this issue. It just PIN don't enter to D3. But codec enter to D3 will not have this issue. When power_save = 1, codec will enter to D3 after one more second. If this time PIN in D3 state, it will show noise from speaker. If set power_save_node = 0, noise was gone. This symptom that I test on ALC225 with external AMP machine. It was not has this symptom.
