How to connect older 5.1 Home Cinema to PC for Dolby Digital etc.

[Phi Karapiperis]

Hello.

I made a new PC after 10 years and I'm looking how to connect my home cinema to it. I'm quite baffled by it. Till now my PC was old so I just had a 3.5mm jack to 2 RCA. I'm looking at what Cable I need. The Home Cinema is an over decade old ass Sony one. All the speakers connect to the amplifier. It supports Dolby Digital Prologic II and DTS. Excuse my shitty phone camera.

This is the rear of the amp where the connection to the PC and the sub is: http/oi66.tinypic.com/nzki6t.jpg
This is the part the speakers are connected:

And this is the rear of the motherboard:

What cable and/or adapter I need to connect them? How in the blue hell is it called because I can't find anything on ebay. Thank you so much for your time.

It looks like it has a toslink optical port on the back, so you would need cheap sound card (Asus Xonar DS) and a toslink cable. I can't fully say for sure though because you don't have a straight on shot of the back panel, or better yet, the model number of the surround device so I could google it.

Sorry, this is the rear, Googled it myself.

My motherboard actually has an optical port. I just didn't think it would matter, sorry I'm clueless. So just this would do? http/www.ebay.com/itm/6-5FT-Premium-Digital-Audio-Optical-Optic-Fiber-Cable-Toslink-SPDIF-Cord-Black-/261740367930?hash=item3cf0f1103a:g:b1wAAOSw2s1UvKTO

That's how I have it connected on my current old PC. There is no surround sound.

If your MB has an optical port then yes just nned to connect your pc to it. Surround sound is only going to come from sources that have surround in them. Media player and most others won't decode a Dolby source so it just ends up in stereo.

I went through the same process with my own PC. 5 sets of RCA cables, and changed them for 1 optical cable.

You'll want something like this:

From there it depends on what your receiver can decode and what your sound card can send, AND what the source is encoded as. You will need to spend a bunch of time messing with settings until you find something that works.
