Sound works just fine on my E100. I haven't done anything special aside from turning up the sound levels in alsamixer.I have updated the c++ dial_tone example, and can successfully use it on my E100 without issue. The updated code is here:https://github.com/bhilburn/gnuradio-on-e100/tree/benchmark_uhd_work/gnuradio-examples/c++/dial_toneNote that the commits for that are kind of scattered about, unfortunately. After updating the dial_tone example, I turned it into a test for something else, and then realized the updated dial_tone on its own was useful and reverted it back. As a result, you probably don't want to cherry-pick individual commits, but just grab the files you want. I could put together a patch that does it, but I'm about to head out for the day.Remember to enable the Makefile and SUBDIR, like the README file says in the dial_tone directory.Hope this helps!Cheers,BenOn Tue, Mar 8, 2011 at 3:36 PM, Ingmar Meins <address@hidden> wrote: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.

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 busyTraceback (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 sinkreturn _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 linux2Type "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?
