This forum is for Audacity 2.x.x on GNU/Linux and Unix-like operating systems.
Please state which version of Linux you are using, the exact three-section version number of Audacity from Help > About Audacity... and whether you installed your distribution's release or daily version of Audacity or compiled Audacity from source code.
Audacity 1.2.x and 1.3.x are obsolete and no longer supported. If you still have those versions, please upgrade at http://www.audacityteam.org/download/
The old forums for those versions are now closed, but you can still read the archives of the 1.2.x
