Huh, can you verify portaudio is in the output of "gnuradio-config-info --enabled-components" ?
Can you add another section,
verbose = true
Just to verify: you're using the "[..]" section headers correctly, and the rest of the conf file looks ungarbled, right?
We might be encountering a case where the config file simply isn't read; as a quick test:
Close all gnuradio-companions, add
canvas_default_size = 100,100
to that file, and open up the companion – your canvas size should now be 100x100px. Is that the case?

Thanks, but I've tried that (setting "audio_module = portaudio"). It doesn't appear to have the desired effect.

Sorry, not currently running any Windows VM, but in the spirit of giving you the info you need as fast as possible:
Quick lecture of the audio sink/source factory tells me that under windows, by default the windows audio architecture is used.
So to use portaudio instead, you need to have a GNU Radio config file (under unixoids, that's ~/.gnuradio/config.conf), and add

I'm using the pre-built Win64 binary of GNURadio listed on the gnuradio.org site. The portaudio library was included as part of the Win64 build, but I can't seem to figure out how to use it instead of the default windows audio. (I want an audio source and the windows audio source does not work.) I've tried putting "audio_module = portaudio" (and "audio_module = audio_portaudio") in the config.conf file, but when I run a simple flowgraph that includes an audio source and sink, I see:
INFO: Audio source arch: windowsINFO: Audio sink arch: windows
in the console and there is no sound. I assume the lines above are telling me that the windows audio devices are being used and not the desired portaudio devices. I have tried leaving the device name in the audio source blank as well as trying "0" and "hw:0,0", but still see the messages above. Can someone tell me how to configure audio for portaudio or is it just not supported?
