I have installed a completely fresh version of Debian Wheezy on my Dell
E4310 Laptop. I have also installed gnuradio via pyboms from the main
distribution last night, as recommended. I also installed gr-fcd.
This is pretty basic and should simply just work. However, the fcd block
does not operate (I have included the udev rule) even the simple
dialtone will not work.
Dialtone gives “RuntimeError: audio_oss_sink” resulting from not being
able to open the audio device. This should be detected automatically but
the result is “audio_oss_sink: /dev/dsp: no such file or directory”.
Well that’s fine as there is no /dev/dsp. Remember this is a deafult
install of Wheezy.
However, I have tried every combination of hw:N,N and the same for
plughw without success. The result is always something like hw:0 No such
file or directory.
I suspect there is something missing from the default installation but
sound works fine in other applications.
