can't play music

I am band-new to Audacity. I have hooked up the AV202-B unit I bought from Amazon, with the cords color-matched, and plugged it into a USB port, but I cannot get any sound out of it when I play my cassette deck.

Try making a sample recording from your built-in microphone first.

Now, delete the recording, plug in your AV202-B, do Transport > Rescan Audio Devices, then select your “AV202-B” in the Device Toolbar, and try again.
