Comment 37 for bug 1970148

I applied the same solution found here https://bugs.chromium.org/p/chromium/issues/detail?id=1315684#c17 using dconf-editor to turn to false org/gnome/desktop/sound/input-feedkback-sounds and this worked for me,
The other solutions (installing portal, disabling hardware acceleration) didn't worked, but this seems to work.
