My current solution is to run the affected script as my non-root user and in it
run some parts with sudo
(set up to run without a sudo password to avoid script interruption).
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
