I have not been able to get sound working (quickly) on my E100 either so
I gave up and plugged in a USB headset which I address as hw:1,0 in python.

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.
