VAST FM Transmitter | No Audio via USB running Windows 10

[tju]

Hi all,
I am using 2 of the VAST INT FM Transmitter and cannot get Audio working when connected via USB to any PC.
I tried:
1. VLC -> Audio Device : HIFI FMT
2. Set the FM Transmitter device as default Audio Device for Windows

NO Sound transmitted over the Air.
The Sound level indicator if the GUI is indicating something.

Did you run a scan in your area to make sure the frequency was unused? You could try externally supplying the 5 volts dc and use the aux input to see it its a windows driver problem.

Some background information:
The device is used to test tuner modules and is directly connected to the antenna input.
In any case, RDS Text and station name is received on the frequency used by the transmitter without issues.
