Loosely speaking, pavucontrol is to Pulse Audio as alsamixer is to ALSA. It's a GUI app. I'm not sure if there exists a strictly text equivalent of pavucontrol. There is also a commandline tool call "pactl". This would allow you to control the Pulse Audio daemon on your child's computer without a GUI (though there is a bit of a learning curve).
