[REGRESSION] Distorted sound on Acer Aspire A115-31 laptop

[Evgeny Kapun <abacabadabacaba@gmail.com>]

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.
