Hi Aj,
I was having a very similar problem as you since swapping over from a Mac to a Windows device for receiving the usb output for streaming. After much searching I discovered that the issue for me was that when installing windows 10, the privacy settings for the microphone was set to default no access. This meant that none of my devices were able to see the incoming audio, and even stopped it from appearing in the windows recording panel for some reason. I was able to get it working by changing the settings in “Microphone Privacy Settings”. Hope this helps.
