Hello again,
thank you for your fast reply!
I tried your solution and can confirm this:

Yes, that's exactly what happens.

This is right too. :)

This is right as well. But the succeeding call

turns off mic-mute LED and speakers. However
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01
turns off speakers and turns mic-mute LED on. Following
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x02
turns on both, speakers and mic-mute LED.
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x04
turns off mic-mute LED and turns on speakers.

Actually it has a playback-mute LED, but unfortunately I have not found
the GPIO pin to activate it.
I tried by first doing SET_GPIO_DIR (with values 0x01, 0x02, 0x04).
Foreach SET_GPIO_DIR I did SET_GPIO_MASK (with values 0x01, 0x02, 0x04)
and foreach SET_GPIO_MASK I did SET_GPIO_DATA (with values 0x00, 0x01,
0x02, 0x04).
I hope this test results help further understanding the pin layout.
Maybe you have some advice to find the playback-mute led?
Best regards
Alexander

Hello alsa-devel-team,
I have a problem with the built-in speakers on the 2020 model of the
hp-spectre. From my unexperienced point of view, the audio sinks are
correctly identified and therefore I tried tweaking the GPIO pins with
success.
Information from alsa-info is here:
http://alsa-project.org/db/?f=c8ee13e52fd6b2377573a7123c2887fe4d59c917
When I use hda-verb with the following parameters 2 of 4 of my
built-in speakers start working:
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x02 (or 0x04)
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x01
So this means that GPIO pin#0 (0x01) is the amp, and it needs to be
cleared.
In addition, my mute-mic-led on the keyboard glows when:
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01 (or 0x02)
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x04
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x04
And this means GPIO pin#2 being the mic-mute LED, inverted (0=on,
1=off).
To check the behavior, try the following:
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x01
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00
this should enable the speaker, and the succeeding call
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01
turns off the speaker.
Also,
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x04
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x04
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x00
turns on the mic-mute LED, and the succeeding call
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x04
turns off the LED.
If above is the confirmed, you can manage both in a shot by
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x05
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x05
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x04
will turn on the speaker but off the LED, and
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x05
will turn on both speaker and LED.
And, doesn't the machine have the playback mute LED? Usually it's
controlled with the GPIO, too, but this case
Since I do not understand how the GPIO-settings are integrated and
applied in the upstream software for corresponding models, I would
very much appreciate any help to get this to work out of the box in
future releases so I do not have tweak my system all the time and
others can benefit as well.
Any suggestions on getting all 4 speakers to work or the
mute-volume-led to glow are very much welcome alike!
The surround/bass speaker is often more difficult. We need either the
contact to the vendor or the reverse engineering.
