[Discuss-gnuradio] Problems with the examples

[Jose Emilio Gervilla Rega]

Hello all!
 
I'm working on OFDM synchronization for GNURadio and we need a file to simulate the OFDM. I thought it would be a good way use the audio_to_file.py of the examples, but it doesn´t work. I speak to the microphone but when I run audio_play.py nothing is listened. I think the problem might be because when I push ENTER the execution of these examples should finish and it doesn't, it continue running until I kill the process (ctrl+c). It occurs with all the examples and I don't know what can be the problem because I've checked the code on the website and it is the same... The lines which should do it are:
 
if __name__ == '__main__':
      try:
          my_top_block().run()
      except KeyboardInterrupt:
          pass
 
I think that it is ok and with these lines the program should stop by pushing ENTER but it doesn't. The microphone problem must be other one but i`m starting to suspect that the file doesn't record fine because of this mistake. Can be useful for you that when I run audio_to_play.py it finishes when the file finishes(last a little of time) although it doesn't sound anything, and it doesn't stop if pushing ENTER.
 
I know these are very elemental doubts and problems but are stopping us of going on with our work and we are not able to solve it.
 
Thank you very much
