Hi, i've encountered an audio problem after the installation of KDE Neon
in my laptop (HP pavilion cw1010nl). I hear a constant noise that is not
showed in pavucontrol and even when all the audio peripherals are
disabled. When i use windows 10 this problem does not occur. I cannot
say in what package i found the bug but i use alsa and pulseaudio. Guide
me if you need other informations for better understanding the problem.
Kernel version: 5.9.8
