I have my mobile telephone connected with a male-male 3.5mm cable to my computer and I wanted to record segments from the radio to the computer with Audacity. This is how I achieved that. And also configuring the alsamixer settings properly to enable the line-in port as the capture source will help with this. This way you can record songs off the radio with Audacity and save them as the free ogg vorbis format to your computer. When you save a file with the export option in Audacity and choose the ogg vorbis output format, you are given the choice to tag the file with ID3 tags. This is a great way to record your old mix tapes or LP records to your hard drive and then burn them to a gold DVDR to archive them. Linux Mint works better than Ubuntu in this regard, the alsa sound comes out of the speaker output on my machine, but the music I play with Pulseaudio applications comes through the HDMI output. I prefer that. This does work very well on my machine and it will work well for you too. So get recording and archive all of those old cassette tapes.
