If the program works normally from that user's account then you need
that user's environment and to get that you use the - (dash) switch. So
your command would look like:
su - user -c "aplay /usr/share/sounds/alsa/Front_Center.wav"
This is why when we switch user to root we use: su -
...to ensure we get root's environment. See the man page for su.
