I have some old cassettes which I would like to convert to cd. When I try to use Audacity, the control for selecting Line-in will not work. Any ideas please?

Welcome to the forums.

Going to move you to our Audio forum Dopie, where you should get more informed answers.

Did you try 'What you Hear ?..

Basically, take the output (external/extra speaker jack) of your cassette player and connect it to the input (microphone jack) of your computer.

Set up the output and input levels…and record

It may be necessary to connect everything first, and [I]then[/I] look for the line-in or microphone control.

Thanks heaps. I have it working fine now. I had it plugged in wrong.
