Re: [Discuss-gnuradio] multi_tone.py

[Robert McGwier]

Good point.

I commented out the offending lines.  If you have portaudio and/or jack, 
they are easily replaced.

#from gnuradio import audio_portaudio
#from gnuradio import audio_jack

and then remove the comment in front of the

dst = audio_jack.sink

and/or

dst = audio_portaudio.sink

if you wish to have local support.  I could easily upload 
multi_tone_allhosts.py, etc.
