Re: [Discuss-gnuradio] gqrx in MacPorts

Hi Alex - In MacPorts (currently), one can install any of the GNU Radio ports 
with PortAudio using the +portaudio or +full variants.  Neither is the default. 
 If GNU Radio is installed with the PortAudio option, can gqrx make use of it?  
Or, does gqrx have to be configured (and built) using AUDIO_BACKEND=portaudio?  
Seems like gqrx might be able to select the audio interface at boot time from 
those available, maybe even tell gnuradio-audio which interface to use?  Just 
trying to think outside the box ... - MLD
