Question 5.1 help

[DARBADARBZ]

I have a Vizio S4251w-B4 (5.1) that has one optical input. I want my TV and PC to be used by the soundbar (one at a time, one turned on at a time). If I use an ASUS XONAR SE and plug it and my TV to one end of the BlueRigger 1x2 Toslink Digital Fiber Optic Audio Splitter 1 and the other end into the speaker, will true 5.1 still work from the speakers from the TV and PC? My goal is 5.1 from TV and PC to one optical. Preferably without crazy dongles and adapters. I don't have the soundcard or splitter yet; I was just looking. Because my speakers can kind of make stereo 5.1, but it sounds better true 5.1 and I'm just using Bluetooth right now.

Optical cannot do 5.1 surround unless the source is using DTS or Dobly encoding. Optical doesn't have enough bandwidth to do raw 5.1 audio.

I though it can do compressed 5.1

That's what DTS and Dolby do.
