Is there a way to change volume of sounds in Pygame Zero?

Question

I'm working on fully fleshing out a game I made following a tutorial, and have been trying to incorporate sound effects into the finished thing. However they are way too loud and I can't seem to find a way to quieten them. I know there's a way in normal pygame but I don't know if there's one for pgzero. Any help would be greatly appreciated :)

Here's a snippet of code in case that helps:

if gem.colliderect(ship):
        sounds.gem_collect.play()
        gem.x = random.randint(20, 1180)
        gem.y = 0
        score = score + 1

I have never used pygame zero. But here is the documentation. Doesn't say anything about setting volume for sound objects, but you can set_volume() for music:

music.set_volume(volume)

Set the volume of the music system. This takes a number between 0 (meaning silent) and 1 (meaning full volume).

You could try to use the set_volume() method on a sound object and see what happens. Maybe it's just not documented well.

if gem.colliderect(ship):
    sounds.gem_collect.set_volume(0.2)
    sounds.gem_collect.play()
    gem.x = random.randint(20, 1180)
    gem.y = 0
    score = score + 1

In Pygame zero's documentation I didn't found a way to control volume using sounds but you can change it in Music.

if gem.colliderect(ship):
        music.play_once(track_name) # you don't need to add track extenstion in it
        music.set_volume(num) # num is any number between 0 (meaning silent) and 1 (meaning full volume)
        gem.x = random.randint(20, 1180)
        gem.y = 0
        score = score + 1

Attention This Music api is experimental and have it's own drawbacks and is only availbale in 1.1 and after. Some of the Drawbacks

MP3 may not be available on some Linux distributions.
Some OGG Vorbis files seem to hang Pygame with 100% CPU.
