Short answer: maybe, it depends a lot on what you need this for.

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.

Disclaimer: this is just an example, Linux compatibility unknown. 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.

Kind regards,
Andrei
