Running a music player via cron

Hello,

Since some Sid update (about 2 weeks), something may have happent in te
audio stack or the terminal because what worked no longer works.

So I am under Sid, MATE desktop, via lightdm, pulseaudio,
systemd, etc. Ont minor thing is that if I run an audio as a user or
root at boot before login invia lightem, audio does not work, but well...

Anyway, here I want to run mpv via a cron job under my regular user. The
command works, but via cron, I get an audio access problem.

The command:
killall mpv;/home/jp/radio 10 100

The result:


TERM environment variable not set.
setleds: Error reading current flags setting. Maybe you are not on the
console?: ioctl KDGKBLED: Ioctl() inapproprié pour un périphérique
TERM environment variable not set.
CTRL+C to exit

Same with:
