Got a new Retround cassette player to transfer tapes to my WIndows 7 pc. I am using the latest version of audacity which I just downloaded. Audacity program doesn’t seem to recognize the cassette player. When I play the cassette I get sound from the cassette player but nothing in audacity. But the monitor green bars bounce around as if something is being received. I am using a Dell xps 8700 pc and using the USB port on the front of the pc.
