Sound.speak("text").wait() terminating before finished

The problem is that Sound.speak() returns espeak instead of play here:

Lines 3440 to 3448 in 55f57ad

    
               def speak(text, espeak_opts='-a 200 -s 130'): 
        
                   """ 
        
                   Speak the given text aloud. 
        
                   """ 
        
                   with open(os.devnull, 'w') as n: 
        
                       cmd_line = '/usr/bin/espeak --stdout {0} "{1}"'.format(espeak_opts, text) 
        
                       espeak = Popen(shlex.split(cmd_line), stdout=PIPE) 
        
                       play = Popen(['/usr/bin/aplay', '-q'], stdin=espeak.stdout, stdout=n) 
        
                       return espeak

Return handle to aplay in Sound.espeak

21a5af4 fixes the problem in the jessie branch. I am not sure though if this will ever get released, since stretch is now our main target. And the problem is not present in stretch anyway.

If you have to work in jessie branch, you can clone a local copy to your home directory:

git clone -b jessie https://github.com/ev3dev/ev3dev-lang-python

and add

export PYTHONPATH=/home/robot/ev3dev-lang-python

to your .bashrc.
