Can't record with Audacity from internet

I am recording sounds from the internet such as music from you tube, or from the radio. When I click the record button it just makes a small line. When I hit select the play button it is just noise like static. When I bring in recorded music from my hard drive to audacity it plays just fine. Thanks for your input.

Moderator note: please don’t piggy back on an existing thread whoch is not identical to your problem - I have split it off for you.

Recording from the internet is a special process. You need to run the play and record sides of the computer at once and then cross them. Some of the newer computers have trouble doing this, but we did write an instruction sheet.
