Getting LedFx to activate when music is played by a cron job

Question

I have been using LedFx to sync leds to music from pulseaudio for about a year and it works great. Once LedFx is running the simple command aplay music.wav makes my ESP32 controlled led strips come alive. However, when the same command is executed as a cron job (and as the same user) the music plays but the the lights do nothing even though LedFx is running. I have also tried using:XDG_RUNTIME_DIR="/run/user/500" & export PULSE_RUNTIME_PATH-"/run/user/$id -u)/pulse" in front of the cron command. Any ideas how I can make it work?

Answer 1

In case anyone finds this useful I solved this by using the perl module: Schedule::Cron to run the command instead of crontab.
