Here's one idea. I know the folks use this on PowerSDR to send the audio 
in and out to various other apps. Basically it emulates some virtual 
sound cards and has an audio repeater built in. So you route the audio 
from the sdr to this, repeat it to your speakers, and send it to 
whatever other apps you need, converting the sample rate as needed 
according to  how you set the app up. You'd set Argo to use this virtual 
sound card, which would be repeating the audio from the sdr to Argo.

You can try it for free but it has a voice message that repeats until 
you register. This might do the job and let you use whatever audio app 
you want on the output of your sdr receiver app.

I like Linrad under Linux too, and it will definitely do what you want 
and more, lots more. But did you know there is a Windows version of 
Linrad too? Looks and works like the Linux version, but runs in Windows.
