How I got my rear speakers to work (logitech z 5500 5.1)

Question

Instead of connecting the black cable into the black slot of my speaker system, I put it in the orange slot and the orange plug in the black slot. I did the same to my sound card, black slot in line 3(center/sub) instead of line 2(rear left, rear right) and orange in line 2. I was amazed that this got it to work. I was on the verge on posting some long ass post saying how i tried everything, but i decided to try something stupid and switch a few plugs that I wasnt supposed to switch. I basically got it working by accident. Im pretty happy

When the Toslink to mini-jack digital cable arrives you would set up the 5.1 audio to the system through Audio MIDI Setup; Apps>Utilities>Audio MIDI Setup.
From the Audio MIDI Setup Help menu;
Configuring speakers for multichannel output
If you have a multichannel audio output system, you can select the speaker used to play each channel.
You must be using an audio output system that provides more than two channels of audio output.
Before you start, be sure you have connected the audio devices to your computer, turned them on, if necessary, and installed any software required by the manufacturer.
1. Open Audio MIDI Setup and click Audio Devices.
2. Choose the audio output device from the Properties For pop-up menu and click Configure Speakers.
3. If you are using an interleaved device with more than one audio stream, you can choose the audio streams you want to use with your speaker configuration.
4. If the stream you select provides enough channels for the speakers you are configuring, you cannot select additional streams.
5. Choose the type of output you want to set up from the pop-up menu.
6. For each speaker in the configuration, choose a channel from the pop-up menu below the speaker.
7. To test the configuration and speaker, click the speaker.
8. When you're ready, click OK.
If the speaker doesn't make any sound, make sure it is connected to your audio device correctly and the audio output is not muted.
