Working for me linux solution written as bash scrips is following:
Code:
#!/bin/sh
PLAY=0
while [ true ]; do
WIN=`xdotool search --title 'please enter'`
if [ -n "$WIN" ]; then
PLAY=1
else
PLAY=0
fi
if [ $PLAY = 1 ]; then
aplay /path/to/sound/file/jdsound.wav
fi
sleep 5
done
It requires
xdotools and
aplay installed (usually from given distribution repository).
Copy code to text file, name it somehow (eg. jdsound.sh), chmod it to 0755, provide wav sound file, replace "/path/to/sound/file/jdsound.wav" part with your sound file path and execute. Sound should appear when window with 'please enter' text in title will be opened.
Tested on gnome (ubuntu hardy).
