I’m running Audacity 2.0.4-alpha-Jan 24 2013 On Ubuntu 12.10
From my daughters account Audacity doesn’t cut correctly. When I try and trim a small piece from the beginning of a recording it does the cut, but it also puts about 5 1/2 seconds of silence after the cut point (losing audio I want to keep).
When I do the same thing on the same file from my account it works correctly.
I compared the .audacity-data/audacity.cfg files between our acounts and all settings are the same except for directory names.
This is driving me crazy - I have no idea what’s wrong.
I suspect that the problem is that the Audacity temporary folder is not writeable from your daughters account.
Go to “Edit > Preferences > Directories”
If there is an option to “use RAM”, that should not be selected.
Check the location of the “Temporary Files Directory”. If that folder is not writeable from your daughters account you will need to either, change the folder permissions so that it is writeable, or change the location used by Audacity for temporary files to a location that is writeable from her account.
To change the permissions / ownership of a project, you need to recursively change all the files and folders in the _data folder, as well as the .aup file. From the command line chmod -R and chown -R are your friends, I’m not sure about GUI tools.
As you found out, Audacity does not currently handle very well the case where writing to a project file structure fails.
