I have no clue how to play sounds from a terminal. It does this:
(actually, not even a terminal, because it runs as a daemon)
$ ffmpeg \
-i /usr/share/sounds/freedesktop/stereo/bell.oga \
-f wav \
- \
2> /dev/null \
| aplay -f cd --quiet 2> /dev/null
rough overview:
a client script (tt) is invoked from the terminal
the client starts a daemon if it is not already running
the client sends the command to the daemon
the client exits
the daemon sounds the alarm when a timer reaches 0
running the client while an alarm is sounding turns the alarm off
the client and daemon talk through zmq (tbh http probably makes more sense)
there is no persistence, alarms are held in memory by the daemon so if it exits for any reason they're lost
