Works perfectly with Fedora Core 20 as a Wine application. Just use a loopback cable from earphones out to line-in. Click the little round red dot in the menu bar and select "Record", a file name box will appear. Give it a file name, click OK and it starts recording. Now go to a whatever streaming audio site or whatever that you want to record and it starts streaming right into your sound card, right out the earphone output, right back into the "line-in" and then gets saved by "Messer" into the file name (default saved as .WAV, have not tried anything else).
