Decided to do more trial and error tests.
I tried multiple amd64 kerels from https://kernel.ubuntu.com/~kernel-ppa/mainline/
It seems that all kernels I tried produce metallic audio, I believe you can easily reproduce this by trying them.
Even the 5.4.52-050452.202007160732 kernel produced metallic sound, while the official Mint 5.4.0-52 kernel produces clean audio.
Official Mint kernel 5.8.0-28 also produces clean audio.
