It’s got to be a setting, can anyone help?

Audacity version? (look in " Help > About Audacity")

Check in the Windows Sound Control Panel in the Recording tab and ensure that your sound card is responding to sound from the tape player (you should see a green meter jump up and down to the sound).
If/when that works, launch Audacity (or restart Audacity), and select the corresponding recording device as the one that is working, in the device toolbar.

well thank you, thank you, that worked, now I have severe echoes, but on the trail now, thanks.

Are you sure that you are choosing the external microphone as Recording Device in Audacity?

You should be aware that the mic port is generally unsuitable for connecting a tape deck. If it is just a mono speech tape it might be acceptable. Please see


pc windows 10 via mic,

If you have a desktop/tower computer with a regular soundcard, use the line-input.

A mic input will “work”, but it’s too sensitive for a line-level or headphone-level signal, and it’s usually low-quality (often noisy) and mono. So, you won’t get the best quality.

And, if your laptop has a single combination mic/headphone jack, you need a 4-conductor TRRS plug to make the microphone connection.

For best results with a laptop, use an external USB audio interface (The Behringer UCA202 is popular and affordable). Note that most interfaces will have different connectors that the computer (the Behringer has RCA connectors) so you’ll need a different cable or an adapter. Don’t get a regular “USB soundcard” because they are like laptops with only mic-in and headphone-out.
