How to get 5.1 surround sound from laptop through TV to Sony BdvE390

[geno correli]

Hi, I am having trouble getting my audio from my laptop to play as 5.1 surround. I have my Laptop with a HDMI running to my Vizio E260mv TV and then a audio optical cable running into my Sony BDVE390 surround sound system. It could just be a configuration problem with my PC's audio settings or something more I am not certain, but clearly need help.
Many thanks!

Generally speaking 5.1 audio would be transmitted seperately from pc to amp, if using RCA (phono) cables you would need 6 of them to carry the six channels of audio or a digital cable that carries them all together

Does your laptop have the correct hardware/ports to support 5.1 audio ?

It has the HDMI, sorry I misspoke the "RCA" cable is a optical audio cable running from my TV to the surround sound system.
