Same issue here. Garbled noises are being heard on top of my music
(playing in the background via Rhythmbox) after starting Firefox and
visiting some random website.
My desktop is an AMD Ryzen on a Gigabyte X570 mobo with an nVidia
GeForce GTX 1060 3GB GPU. Like others noted, the noises seem stop for a
while when I change the Output Device from "Line Out - Starship/Matisse"
to "HDMI / DisplayPort X - GP106 High Definition Audio Controller". But
after some minutes playback (or perhaps visiting some other page with
firefox?), the garbled noises appear again... Also, like others, the
noises disappear if I close Firefox...
