Speaker and Headphone Output
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
One of the most frequent (and obvious) bugs with HD-audio is the
silent output from either or both of a built-in speaker and a
headphone jack. In general, you should try a headphone output at
first. A speaker output often requires more additional controls like
the external amplifier bits. Thus a headphone output has a slightly
better chance.
Before making a bug report, double-check whether the mixer is set up
correctly. The recent version of snd-hda-intel driver provides mostly
"Master" volume control as well as "Front" volume (where Front
indicates the front-channels). In addition, there can be individual
"Headphone" and "Speaker" controls.

Ich habe ebenfalls eine Soundkarte (vermutlich OnBoard) mit Intel-Chip, allerdings ein älteres Modell.

Habe gerade noch einmal gesucht. Hier bin ich fündig geworden:
Einstieg:
http://www.kernel.org/doc/Documentation/
Suche nach "Sound/" (Hypertext, einfach runter scrollen)
Gehe ins Directory "alsa"
Öffne Datei "HD-Audio-Models.txt"
Suche nach ALC***
Wenn Du nicht fündig wirst, was ich vermute, dann hilft eventuell ein "Downgrade" des Codecs?!?
Bei mir hat folgendes geholfen. Ich habe laut wiki "
https://wiki.archlinux.de/title/Hda-intel" die folgende Zeile der Datei /etc/modprobe.d/sound hinzugefügt:
options snd-hda-intel model=auto enable=1 index=0
