imac not playing audio from pyle unit

i purchased a pyle pt-659du unit so I can convert cassettes to mp3s on my mac os x el capitan 10.11.5. per instructions, I downloaded audacity 2.1.2.0 and both lame plug ins. connected via usb, inserted a cassette and pushed play. nothing. previous versions (ion) automatically played back through my mac. I can see this is a bit more sophisticated. any assistance would be appreciated.

I can see this is a bit more sophisticated.

Or maybe not. Audacity checks for new connections when it starts. So connect the unit and let the Mac get used to it and then start Audacity. You may still need to tell Audacity to go looking for the player with the Device Toolbar.
