Have you unmuted all columns in alsamixer for user daughter (green 00 under each column)? Have you tried turning up the volume (because there exists some kind of "no sound below a volume cutoff" bug). What output is shown, if any, in the pavucontrol Applications panel when playing, or attempting to play, a wav file? What output is shown in the application itself? It isn't clear to me by what means you're verifying that your daughter has no sound. mplayer, vlc, aplay, browser? All of the above? Warnings? Error messages?
