Dear All,
I am trying my hands at GNU Radio on Ubuntu 10.1. I have been successful in
installing GNU but am not able to use Audio sink in GRC. The error message
is:
*audio_alsa_sink[hw:0,0]: Device or resource busy
Traceback (most recent call last):
File "/home/praphul/top_block.py", line 42, in <module>
tb = top_block()
File "/home/praphul/top_block.py", line 28, in __init__
self.audio_sink_0 = audio.sink(48000, "", True)
File "/usr/lib/python2.6/dist-packages/gnuradio/audio_alsa.py", line 321,
in sink
return _audio_alsa.sink(*args, **kwargs)
RuntimeError: audio_alsa_sink*
I have tried several sampling frequencies for Audio sink and error is
similar. Also, the dial_tone.py is returning following error:
*gr_vmcircbuf_createfilemapping: createfilemapping is not available*
Please help and suggest solutions
-- Praphul
