mpv doesn't cause other programs to induce pops. mpv is more robust against pops than web browsers. ALSA loopback is inherently unreliable.
I suspect a high quality USB soundcard could potentially solve the issue.

I uninstalled mpv for exactly this reason. Everything would work and
then after a while pops and crackles starts. When I go to top, I then
see mpv is at 100% cpu.
I uninstalled it and the pops went away.
Might solve your problem or might not. it was a problem here.
