5.1 speaker help!!

post #1 of 2
Thread Starter 
Hi

Currently i have the Logitech X530 5.1 Speakers. connected to my PC via the 3 RCA inputs.
It works great and i get 5.1 sound.

I then got a optical cable from my ps3 to a optical to coaxial converter and put the coaxial cable into my PC's input (this is because i don't have a optical input on my PC) I then set my PC to play the audio from the optical to my speakers. It worked okay on stereo and i would get sound but when i changed to 5.1 or 5.1 dts on the ps3 all i get is a loud buzzing noise. I know its not my speakers as my computer plays 5.1 through it properly ( i tested it out in left 4 dead 2).

Also on the realtek audio manager on digital input it says AC3 (which is 5.1 surround sound) This is really frustrating as i don't have enough money for a home cinema (which is why i tried to connect through the computers) and my speakers also only have RCA input.

The problem seems to be from the computer to speakers as i think the sound isn't being decoded and sent through each RCA cable separately.

Is there anyway to fix this as i really want to get this working.

Thanks in advanced!

Edit: Basically the sound from pc to speaker works in 5.1 but the sound from coaxial (ps3) to computer to speakers only works on stero and on 5.1 i get only a buzzing noise.

I have set my ps3 up properly. i set it to enable outputting of 5.1, stereo and DTS through optical, and in game when i change it from stereo to any of the above i get the the noise.

Heres a pic of my setup. oh and its x530 not x30.
