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 <module>
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.)
