At a minimum your system must have a S/PDIF output (obviously). Then you must somehow convince your system to generate AC-3 output as regular output to the ALSA spdif/iec958 output is two channels only[1]. Kodi (and probably everything else based on ffmpeg) can do so for at least FLAC and AAC 5.1 audio (tested). It should be much easier to address a specific channel with an audio device with 6 (or recently 8) analog outputs, like this[2]. You should also get individual 4 independent volume controls (Front, Surround, Center and LFE). [1] at least for my audio devices 'speaker-test' only accepts '2' for the '--channels/-c' parameter for all digital outputs, but the 'surround51' analog output accepts 2, 4 and 6.

It's probably a good idea to buy something like this only from sellers that allow quick and easy returns, no questions asked, just in case it doesn't work well for you.
