No success using Audacity to record from USB cassette deck

I am unable to get a cassette in a USB cassette player to be inputted into Audacity. I have tried every thing I can find to get me going but no luck. I have been successful with vinyl utilizing a USB turntable, but not a USB cassette. Can someone help me get started? thanks

Let me guess. This is a $40 “Cassette-to-USB” device. It shows up in Mac System Settings > Sound > Input as “PnP Audio Device” or something similar.
No-one we know of has been able to get one of those things to work on Mac.

In any case, you should check the Mac System Settings Sound > Input panel to see if the Mac can see the device, and can see it reliably (reports are that the device appears and disappears).
