If you can login as your child (i.e., same user account as him) on his Linux system (ssh with X forwarding), then you should be able to run "pavucontrol". 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).
