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
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
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!
Thank you very much!
Alexander
