Simple mixer control 'Master',0 Mono: Playback 19 [22%] [-51.00dB] [on]

This is rather low. A lower signal level implies a worse signal-to- noise ratio.

It is also hearable, with the volume turned up higher and when nothing is playing.

...

Simple mixer control 'Mic',0 Front Left: Playback 0 [0%] [-34.50dB] [on] Front Right: Playback 0 [0%] [-34.50dB] [on]

This plays any noise from the mic input.

Turning it off makes no difference since capture is turned off anyway:

This plays any noise from the mic input.

Turning it off makes no difference since capture is turned off anyway:

This is a loopback mixer element, it has nothing to do with capture stream.

The likely culprit of the static noises is the signal from the analog loopback. In some cases, you can disable the whole loopback via "Loopback Mixing" mixer element on the fly. In some cases, you'd need to disable each mixer input (e.g. "Mic Playback Switch"). In some cases (e.g. on some Sony and Dell laptops), you'd need to disable the complete analog loopback at the initialization.

The last one can be done via the early patching or sysfs reconfiguration, pass "mixer_nid = 0" hint. See HD-Audio.txt for a brief instruction.

Sadly, that did not help.

Cheers, Julian

Give alsa-info.sh output after your change to verify whether you did correctly.

This is a loopback mixer element, it has nothing to do with capture stream.

The likely culprit of the static noises is the signal from the analog loopback. In some cases, you can disable the whole loopback via "Loopback Mixing" mixer element on the fly. In some cases, you'd need to disable each mixer input (e.g. "Mic Playback Switch"). In some cases (e.g. on some Sony and Dell laptops), you'd need to disable the complete analog loopback at the initialization.

The last one can be done via the early patching or sysfs reconfiguration, pass "mixer_nid = 0" hint. See HD-Audio.txt for a brief instruction.

Sadly, that did not help.

Give alsa-info.sh output after your change to verify whether you did correctly.

Here it is, cheers:

Thanks. The setup looks OK, the path is: DAC (0x02) -> mixer (0x0c) -> mixer (0x14) and the mixer mutes the loopback path (index 1).

Is it the state where you still hear the static noise?

Yes, the alsa-info.sh script was executed, while hearing the static noise.

Also, what if you use the module option for snd-hda-intel model=nofixup or model=generic?

That did not change anything either. Passing the "mixer_nid = 0" hint also did not get rid of the static noise, when loading snd-hda-intel with model=nofixup resp. model=generic.

Yes, the alsa-info.sh script was executed, while hearing the static noise.

OK. And if you mute "Speaker" or "Headphone", the noise is gone, too, right?

No, if I mute "Speaker" (the internal laptop speaker) it is not gone. It is only gone, if I mute "Master" or have a headphone plugged in and mute "Headphone" or "Master".

More fascinating, it is not present, if the speaker is not muted and I disable powersaving via "echo '0' > '/sys/module/snd_hda_intel/parameters/power_save'" but even then, it is still present on the headphone.

Did you reboot with setting the option in /etc/modprobe.d/*? Reloading the module might not work for such a problem.

No, I just unloaded every sound-related module and than loaded the module via "modprobe snd-hda-intel model=..." again.

In either way, there should be some difference in alsa-info.sh output, e.g. more (or less) mixer items with the model option.

The difference is their, all the "Dock ..." entries were missing, when loading with the model="..." option.

Interesting. The "Speaker" mute changes "Speaker Playback Switch", and as you can see in alsa-info.sh output, this toggles the mute of the speaker pin NID 0x14, i.e. the endpoint. If "Master" influences, it means to mute *both* Headphone and Speaker mutes would work. Could you check this?

Muting both Headphone and Speaker does not work for the static noise on the speaker.

Then check what's the difference in codec proc content between the two cases: Master=mute and Headphone+Speaker=mute.

Hm. Is the noise audible when you playback a PCM stream, too? For example, you can play a silent stream.

Yes, then it is audible.

Also, what if you use the module option for snd-hda-intel model=nofixup or model=generic?

That did not change anything either. Passing the "mixer_nid = 0" hint also did not get rid of the static noise, when loading snd-hda-intel with model=nofixup resp. model=generic.

Did you reboot with setting the option in /etc/modprobe.d/*? Reloading the module might not work for such a problem.

No, I just unloaded every sound-related module and than loaded the module via "modprobe snd-hda-intel model=..." again.

Then always test with reboot. The problem is about the vendor-specific setups, and it's often sticky unless the cold boot. At best, do the cold boot. The warm boot doesn't cure always.

Ok, I tested with a reboot but that did not help.

In either way, there should be some difference in alsa-info.sh output, e.g. more (or less) mixer items with the model option.

The difference is their, all the "Dock ..." entries were missing, when loading with the model="..." option.

Yes, and you should also see the difference in the kernel messages.

Another thing to check is to swap the DAC assignment. There was a similar problem on some Sony laptops, and we had to swap the DAC assignment since the hardware seems to have some implicit assumption of the DAC. A test patch is below.

Thanks, but sadly the patch did not help.

I have no much other clue, so far. The rest you can test is to toggle EAPD, toggle GPIO pin, and change the different pin setups, e.g. put VREF or HP amp bit on any (even unused) pins.

OK. And if you mute "Speaker" or "Headphone", the noise is gone, too, right?

No, if I mute "Speaker" (the internal laptop speaker) it is not gone. It is only gone, if I mute "Master" or have a headphone plugged in and mute "Headphone" or "Master".

Interesting. The "Speaker" mute changes "Speaker Playback Switch", and as you can see in alsa-info.sh output, this toggles the mute of the speaker pin NID 0x14, i.e. the endpoint. If "Master" influences, it means to mute *both* Headphone and Speaker mutes would work. Could you check this?

Muting both Headphone and Speaker does not work for the static noise on the speaker.

Then check what's the difference in codec proc content between the two cases: Master=mute and Headphone+Speaker=mute.

More fascinating, it is not present, if the speaker is not muted and I disable powersaving via "echo '0' > '/sys/module/snd_hda_intel/parameters/power_save'" but even then, it is still present on the headphone.

Hm. Is the noise audible when you playback a PCM stream, too? For example, you can play a silent stream.

Yes, then it is audible.

Toggling the EAPD got rid of the noise but I also did not get any sound output anymore. Playing with the other pins got me nowhere. Seems like I have to live with the noise.

Possibly a combination of something might work, but it needs really many trial-and-error. In anyway, if you hit a good state coincidentally, don't forget to take alsa-info.sh snapshot.
