Description Andrew Wilkie 2024-01-29 00:49:34 UTC

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

Then please bisect the kernel (see LKML post at [1] for a guide).

... and give more detailed logs.

Run alsa-info.sh with --no-upload option and attach the output (don't paste) to Bugzilla for both working and non-working cases.
