[Help] Audio crackles when CPU is under heavy load and music is in the background

apps tested: minecraft, vlc(flatpak), spotify(flatpak), other fltapaks
crackles on both bluetooth and minijack headphones,
disabling microphone, easyeffects, gpu screen recorder ( gsr-default_output) didn't help
I use blender to put the load on CPU but it also happens when compiling or gaming
I have increased stuff in cat /etc/pipewire/pipewire.conf

What are reccomednded robot control theory textbooks?
I would like to know more about theoretical side of robotics as I so far had only the practical experience.
I also could be interested in lectures on YT.
