[MPlayer-users] two sound files at the same time - problem with crontab (mplayer involved)

[Roger Heflin]

To run audio from another session (ie cron or an ssh login) you need to set
all sorts of stuff for pulseaudio to work even if it is the same user.
Cron has none of that environment set.  There may be something else in
addition to the environment, or it may simply be just environment vars.

I cannot tell you what you have to set as I have not wanted it to work bad
enough to sort it out.

Without that it does not know where the sound goes, nor where the video
goes if something has video.

You might be better off making a shell script to do the same thing and
starting it up from the interactive session.
