Add LFE on stereo downmix


By default, Kodi discard the LFE channel in stereo downmix, but some of us have good full range speakers and would want to add some LFE.

wxstazy LibreELEC builds for Amlogic boards add an option for that, so it is possible. The only problem with his version is it doesn’t prevent prevent clipping from the addition of a new channel, forcing the user to lower the volume globally.
