Audio with CRON works - not AT?

[Philip Rhoades]

People,

When I put:

40 21 * * * root /usr/bin/mplayer -ao alsa 
/home/phil/audio/vincent_van_gogh.mp3

in /etc/crontab - it works but if use "at" for any time and enter:

/usr/bin/mplayer -ao alsa /home/phil/audio/vincent_van_gogh.mp3

- at the designated time I hear a click as though something happens but 
no audio clip.

Anyone know why "at" doesn't behave?

Thanks,

Phil.
