Although I don't approve of habitually running as root, I have a suggestion that
might help. Years ago I created a little script to play an .mp3 as a wake-up alarm, but
there was a little problem. I have my box set to turn itself back on after a power drop
if it was on before, but if it happens late at night, I won't be logged in in the
morning, and there wouldn't be any sound. However, I learned by experiment that
ffmpeg can produce sound even if nobody's logged in. If so, it should be able to do
what you're looking for.
And it works too:
$ sudo ffmpeg -i /audio/ogg/beginning.ogg -f alsa default -loglevel quiet
ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused
$ aplay -l
