Open the text editor with the command:
nano /etc/modprobe.d/intelDSP.conf
Inside the file, add the following configuration line:
options snd-intel-dspcfg dsp_driver=1
Save the changes and reboot your system. Hopefully, this configuration will resolve the issue. It's currently working on my Matebook d14 with Ubuntu 22.04 and kernel 6.2.0.
However, if this doesn't fix the problem, for some reason, I found that version 5.15 of the kernel works just fine.
Простой пороговый фильтр должен помочь.
Берем точку и квадратик вокруг нее и считаем плотность, если плотность не превышает некий порог, точку зануляем.
