It’s not subtle when all if the desktop plingplogs all the time about everything. Those things should be off by default and turned on only on demand in the accessibility settings for the visually impaired.
If it doesn’t matter for some and it’s an annoyance for others, it should be off and visually impaired people who rely on that can turn it on (unless their screen reader tells them anyway, then a second sound is useless for them as well).
