Dear Tom,
I backtraced this call and there is no implementation of gnuradio
preference file. When it is called the architecture, it returns
gr_prefs::singleton()->get_string("audio", "audio_module", "auto");
Thus, get_string is implemented as this:
const std::string
gr_prefs::get_string(const std::string section, const std::string
option, const std::string default_val)
{
return default_val;
}
As you can see, it does not parse any value of any config file. It just
returns the default value. Even though it is implemented in a different
way in Python (it is a python written module), in C++ there isn't.
So, are you going to implement it? Have you plans to make working it?
Thanks.

Pol,
That's one of the problems with working in two languages and having
some things defined one place and others in another place. It looks
like the Python and C++ preferences don't behave exactly the same.
Instead of putting the configuration info into your home directory
('~/.gnuradio/'), try putting it into the system configuration
directory ($prefix/etc/gnuradio/conf.d) into the gr-audio.conf file.
