I just installed gnuradio using pybombs, and the install appeared to  
complete with no errors.

When trying to run dial\_tone.py, I receive the following error:

audio\_oss\_sink: /dev/dsp: No such file or directory  
Traceback (most recent call last):  
File “./dial\_tone.py”, line 61, in   
my\_top\_block().run()  
File “./dial\_tone.py”, line 55, in **init**  
dst = audio.sink(sample\_rate, options.audio\_output)  
File  
“/home/aryoung/work/target/lib/python2.7/dist-packages/gnuradio/audio/audio\_swig.py”,  
line 122, in make  
return \_audio\_swig.sink\_make(\*args, \*\*kwargs)  
RuntimeError: audio\_oss\_sink

I have tried using the flags ‘-O hw:0,0’ and ‘-O plughw:0,0’ with no  
success. I am running on Ubuntu 12.04 64bit, and have verified that the  
audio works otherwise (played some internet radio.)

Any ideas about what’s going on here?

Thanks,  
Alex Y.

Hi Alex,  
the dial\_tone.py that comes with my version of GR from the git  
(docs/exploring-gnuradio/dial\_tone.py) uses the audio\_sink, and not the  
audio\_oss\_sink, and works quite fine on an alsa-only system.  
Generally, when I grep my git repo for “oss\_sink”, only  
gr-audio/lib/oss/oss\_sink.cc matches. Most probably you’re using an  
ancient version of that script, where did you get that?

Greetings,  
Marcus
