I am using an Acer Aspire A115-31 laptop. When running newer kernel versions, sound played through headphones is distorted, but when running older versions, it is not.
Kernel version: Linux version 6.12.5 (user@hostname) (gcc (Debian 14.2.0-8) 14.2.0, GNU ld (GNU Binutils for Debian) 2.43.50.20241210) #1 SMP PREEMPT_DYNAMIC Sun Dec 15 05:09:16 IST 2024 Operating System: Debian GNU/Linux trixie/sid
No special actions are needed to reproduce the issue. The sound is distorted all the time, and it doesn't depend on anything besides using an affected kernel version.
It seems to be caused by commit 34ab5bbc6e82214d7f7393eba26d164b303ebb4e (ALSA: hda/realtek - Add Headset Mic supported Acer NB platform). Indeed, if I remove the entry that this commit adds, the issue disappears.

Headphone or Headset. Which did you use? I don't know your platform has headset mic support or not.
I use headphones (no mic). I suppose my laptop should support a mic, because there is an icon next to the headset socket which shows a headset with a mic.
Could you record sound via headphone?
I want to know how the voice distortion.
I've run some experiments to determine the nature of the distortions, and I found that on affected kernels, what I'm hearing is the difference between the left and the right channel of what is playing. So, if I play a mono sound, I hear nothing at all (or rather, almost nothing). If I manually mute one of the channels, I hear the sound normally (through both ears, while on older kernels muting individual channels actually works). If I invert one of the channels, I hear the sound normally as well. If I play a stereo sound (for example, a music track), I hear distortions.

Hi,
I already posted alsa-info output in a previous message:
Broken, kernel version 6.12.5: https://lore.kernel.org/linux-sound/0625722b-5404-406a-b571-ff79693fe980@gma... Working, kernel version 6.7.11: https://lore.kernel.org/linux-sound/0625722b-5404-406a-b571-ff79693fe980@gma...
Or do you need alsa-info with a new kernel, but with the offending commit reverted?

Here are two alsa-info outputs for the same kernel version, except that one has the problematic commit reverted.

This patch, when applied to kernel version 6.12.8, appears to fix the issue. There are no distortions, and the left and the right channel can be controlled independently.
Here is alsa-info output with and without the patch. The distortions only occur without the patch.
