Sorry guys, some more information. Having just today re-checked it out, I can advise that for Ubuntu and LinuxMint, you also need gstreamer LAME plugins etc installed, most easily achieved by adding ubuntu-restricted-extras, which I am in the habit of always doing, if only to get MicroSoft Core Fonts installed, to ease cross-platform interoperation.
For the real techies amongst you, gst-inspect lame will then lead you on to the LAME plugin commands that are applicable to that specific implementation of Linux LAME, so have fun !
