Touble with subprocess

[jake9wi]

Hello, I am trying to write a script that calls a program to play audio and then restart the program so often.

However the program is not being killed and respawned?!

"""
Playback an audio stream.

Here we want to playback audio untill the user
presses ctrl+c.  If we do not restart our playback
process every three hours the server providing
the audio may start giving us silence.
