I tried VLC player using its create audio stream wizard. It doesn't appear to do anything on any computer. I hit create stream, the wizard closes, and VLC just sits there like dumb to whatever I did in the wizard.
Also tried creating a windows shortcut using this command:
On the Laptop:
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" dshow:// :dshow-adev="Stereo Mix (Realtek High Defini" :dshow-caching=200 --sout "#transcode{vcodec=none,acodec=mp3,ab=320,channels =2,samplerate=44100}:http{dst=:8079/st.mp3}"
VLC just crashes. But at least now Windows Firewall asked to give VLC permission, progress I guess.
On the Desktop:
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" dshow:// :dshow-adev=""What U Hear" (Creative SB X-Fi" :dshow-caching=200 --sout "#transcode{vcodec=none,acodec=mp3,ab=320,channels =2,samplerate=44100}:http{dst=:8079/st.mp3}"
VLC says something like invalid sound device
To see if anything has happened while the laptops VLC player was sitting dumb when it was supposed to be doing something, I connected the desktop VLC to the laptops supposed streaming address,
http://192.168.180.44:8079/st.mp3 and the Desktop VLC crashes.
The only thing VLC seems to be good for is crashing. Even when following guides exactly, on both computers.
