@sergiodavies - You seem to have four DisplayPort monitors connected. If this is the case, you have a different bug. Nevertheless, I can advise here that support for DisplayPort audio on AMD Radeon hardware is finally available in the upstream Linux 4.0 kernel.

A PPA of the 4.0-rc2 kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how to install and uninstall it are at https://wiki.ubuntu.com/Kernel/MainlineBuilds
