I suspect a pulseauio issue. Me too. What does it say with -ao pulse ? I suspect $PULSE_SERVER is not set and mpv cannot find the server started in your graphical session. I would find its contents in my graphical session, put it in the crontab and if it works, come up with a script to guess it. Thanks, Alex

Yeah, the quoting is rather messed up there. In fact, the whole command
is rather suspect, for several reasons. Best to discard it.
I believe the intent was to do something like this:
if pids=$(fuser /dev/dsp 2>/dev/null); then
echo "the following processes are using /dev/dsp:"
for pid in $pids; do
ps -o pid= -o args= -p "$pid"
done
else
echo "no processes are using /dev/dsp"
fi
One may adjust the ps -o options as desired.
(I wrote this for sh, not bash. Had I written it for bash, I would have
used arrays and a dynamically generated single ps command, instead of
an unquoted list-in-a-string and multiple ps commands.)

hmmm I get:
awk: line 1: syntax error at or near )
I added the lines before:
echo CTRL+C to exit && $S

To listen music under bash I always use cvlc from program vlc. Maybe a other possibility.
