K3b

Known Bugs
Although normalize-audio is installed and available, K3b cannot find it and keep asking to install it (sudo apt-get install normalize-audio).
There is a workaround for this issue.

create normalize-audio in the /usr/local/bin/ and put the following script.
#!/bin/bash
case "$1" in
--version)
/usr/bin/normalize-audio --version | sed -e 's/normalize/normalize-audio/g'
;;
*)
/usr/bin/normalize-audio "$@"
;;
esac
make it executable.
$ chmod a+x /usr/local/bin/normalize-audio
If it doesn't work, open K3b -> Configure K3b -> Programs -> Select the "Search Path" tab -> move /usr/local/bin/ up to position it before /usr/bin/.
