Do you have an example configuration? What version of the fdk-aac library are
you using? The latest version commonly used in Linux is v2.0. I am currently
using v1.6 and not having any obvious cut off issues using ffplay or VLC
players. I did have problems with older versions.

Unless you are doing multiple channels like 5.1/7.1, AAC 320kbps is kind of
moot point and you should look towards FLAC.
