I rosmake sound_play (a package in stacks)
after having installed all the needed dependent packages

I started sound_play (roslaunch sound_play soundplay_node.launch)
as indicated in the README file 
(I checked also that my sound board was working! FESTIVAL is OK!)
and
I started test.py (rosrun sound_play test.py)
and i got no sound and the folloqing error!
