| Hi,
I am new
to using GNUradio and the USRP hardware. I installed GNUradio, GRC
and UHD on the E100. I have run the examples for the UHD
and it is working without any problem. From the GNUradio
examples, When I tried running the dial_tone.py, I get
the following error:
audio_alsa_sink[hw:0,0]: Device or resource busy
Traceback (most recent call last):
File "./dial_tone.py", line 55, in <module>
my_top_block().run()
File "./dial_tone.py", line 48, in __init__
dst = audio.sink (sample_rate,
options.audio_output)
File
"/usr/local/lib/python2.6/site-packages/gnuradio/audio_alsa.py",
line 329, in sink
return _audio_alsa.sink(*args, **kwargs)
RuntimeError: audio_alsa_sink
Also,in
python, the importing of modules is working:
Python 2.6.5 (r265:79063, Dec 14 2010, 12:41:31)
[GCC 4.5.2 20101204 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license"
for more information.
>>> from gnuradio import gr
>>> from gnuradio import audio
>>>
When I
go to System--> Preferences --> Sound, a window
pops up that says 'Waiting for sound system to respond'.
Does this mean that there is no sound system?
How can
I verify that my GNUradio install on the E100 is done
right?
Thanks,
Divya.
