I’m running Ubuntu 14.04 and Audacity 2.0.5, during editing of a sound file if I delete a section of sound and then save without moving the position of the editing line. A click is introduced to the sound file about every 1 or 0.5 seconds. If I delete a section of sound and then move the editing line to a different position along the sound wave I don’t get the clicking sound. Is this a bug within Audacity or something within the workings of Ubunu. If I forget to move the editing line before saving and a clicking sound is introduced during playback. I have to shut down Audacity and then reboot it to get rid of this clicking sound. Examining the sound wave when the clicking sound is present I don’t see any indication of anything added to give a clicking sound so it must be associated with a bug within the program.
In case any of these clicks are permanent or some players produce the clicks and some don’t, please be aware of the following good editing practices: http://manual.audacityteam.org/o/man/faq_editing.html#clicks . Definitely Normalize the file with DC offset removal on, before editing it.
Other than that it must be a playback problem. Please post the complete information from Help > Audio Device Info… .

My clicks are not permanent. Also they repeat every 1 or 1.5 seconds as I play the audio file. When I shut down the program and then restart there are no clicks. So it is related only with the program and not with the audio file.
