Help! Trying to use 5.1 PC speakers with my TV

[e-ras-e]

When I bought my new TV (Philips 50PUS7383/12) I thought it would be a good idea to dust of the old, but fully functioning, 5.1 audio system from my old desktop (Logitech x-530). The only problem is that the TV outputs either toslink or hdmi while the speakers have 3x 3,5.mm connectors (green, black & orange) 

 

As far as I have been able to find there are no converters that do this. So I'm wondering wether it is possible to frankenstein something together by cannibalizing parts from the old computer or something like that or if I should just give up on this idea.

If you get yourself one of these you can go 3x3.5mm to RCA and then RCA - single 3.5mm. From what I found online that TV has a headphone out on it. 

EDIT: Quick edit, Orange is Center/Subwoofer, Black is Rear Speaker, Green is normal Speaker/Line-Out, just so you know. Also, don't get THAT adapter $30 is outrageous.

@Kdog If i'm interpreting the use of that adapter correctly, it doesn't actually let you use surround sound, it just provides stereo expansion to a 5.1, which may let OP use the speakers, but not as a 5.1.  Plus he said his TV is only TOSLINK or HDMI out.

OP:  I don't think there are any simple solutions to what you want to do unfortunately.  Things aren't always perfect with TOSLINK either due to most content these days relying on HDCP, and HDMI with an audio return channel (ARC) is kind of the name of the game for receivers.

I would just show my speakers into a hole in my tv till I could hear sound but my tv wasn't new

I believe you're correct. I must've misread that :/. Either way, his tv does have a headphone out on it. If you look at the image with the port diagram on it on this page there's a headphone out.

So a 1/8" to RCA to the adapter you showed and OP can at least get fuller sound if not surround. Probably a similar experience to a soundbar for cheaper!

I probably should have remember to add that I do have an adapter from 3x 3,5mm to RCA and a RCA to single 3,5mm cable (and yes, there is a headphone jack on the tv) so I can use the speakers. However, since a headphone jack only outputs 2 channel audio I can't get 5.1 output this way and I would like to be able to use the speakers to their full potential. 

 

Two of the hdmi ports on the TV have ARC (I did not include it the first time as I did not know what that implied) if that makes a difference. 

 

The only way I have been able to sort of solve this is to connect the speakers to a PC and plug that to the TV with hdmi. But then the speakers will only work for audio from the computer but not for the regular TV-broadcasts. That's why I want to connect the speakers directly to the TV. 

 

As I wrote in the original post I do have an old PC that I could use for parts if that is possible. Even if I will have to solder something together I am willing to do that.
