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_tone <https://github.com/bhilburn/gnuradio-on-e100/tree/benchmark_uhd_work/gnuradio-examples/c++/dial_tone>Note 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!
