All I get is the audio to the speakers. Radio Feed and Proscan both look for audio on an input device like MIC or Line IN. Radio feed shows no audio input running VLC.
I tried Radio Feed Using both Source Client and Web server as input and NOTHING shows.
VLC is outputting to either your speakers or "default audio device". RadioFeed is looking for input on something else, probably "line in". This is a case of telling either VLC to output to a different place or RadioFeed (or Windows) to look for audio in a different place, or both.
It's actually Windows that generally determines what audio is passed to a "recording" program (or streaming programs like RadioFeed). Right-click on the speaker icon in your system tray and choose "Recording devices". Depending on your sound card, you will see something like "Speakers", "Stereo Mix", or "What U Hear" or something like that as an option. Right click on that and "Set as Default Device". Click OK on all the open windows, restart both VLC and RadioFeed, and you should be streaming from RadioFeed's "Source" tab.
(You might be able to bypass all this by just changing the "Input Sound Device" on your "Source" tab to the speakers (or above named) settings. I've never tried it without setting Windows up first.)
The downside of all this is that you will be streaming everything that comes out of your computer's speakers, including Windows' various beeps, dings, and bonks, and potentially your microphone too if it is enabled. The former is a nuisance to your listeners, the latter is actually a TOS violation IIRC. So it is probably better to have VLC send to a different place other than Speakers, and have RadioFeed listen on that.
A (relatively) easy way to do that is to install a virtual audio cable. There is a program called exactly that, which creates an extra audio port in software on your computer. Once that's installed, you would go into VLC and in the "Audio" menu, under "Audio Device", choose "Line 1 (Virtual Audio Cable)". Then you would configure RadioFeed (or Windows, as above) to listen on the same port. You won't hear the audio on your computer, unless you select the "Listen" option in the audio properties (right-click on speaker, as above).
