Hi! Bagas (many thx!) pointed me to a report about a sound regression
with 6.7: https://bugzilla.kernel.org/show_bug.cgi?id=218429
The reporter did not bisect the issue. But maybe you folks might
nevertheless be interested in this or even have some idea what might be
wrong. That's why I decided to write this mail, as quite a few kernel
developer miss if a report for their subsystem is submitted to
bugzilla.kernel.org.
To quote from the comment with the initial report:
> 2020 Asus ROG Strix G17 Laptop - Model: G712LV
> Intel i7 10750H Comet Lake CPU
> 16GB DDR4 RAM
>
> Issues with Intel HD Audio controller
> Fresh install of any Linux distro leaves no audio from Intel HD Audio controller.
> Controller is detected and Linux thinks audio is playing, but nothing comes out of speakers.
>
> Custom modprobe needs to be created to restore basic sound output functionality.
> Add "options snd-hda-intel model=asus-zenbook" to /etc/modprobe.d/alsa-base.conf
> This allows for audio output, but volume is either 100% or 0%. There is no volume control.
>
> The above setting worked fine with both pulseaudio and pipewire under kernels from 5.14-6.6. This no longer works under kernel 6.7
