PS3, S/PDIF output to computer

Recently posted this on a forum but I figured this might be a good place as well:

Goal:
5.1 output from my PS3 through my computer.
Why? I don’t have any other way to output to 5.1 from it without spending money (receiver + different speakers).

What I have:
First gen PS3, HDMI and TOSLINK cables.

Monitor has HDMI -> analog stereo output
Problems: Constant low hum (monitor has bad quality output) and only 2.0 sound. This requires the monitor to be on HDMI output to passthrough audio as well.

This motherboard. It has a Realtek ALC888 chip. I also have the separate bracket for TOSLINK in.
Problems: This can do stereo but no DTS/Dolby, but it fixes the buzzing problem. It can also play when the monitor is on different output.

And a Creative X-Fi Extreme Audio card.
This has S/PDIF in, but I am not spending $100+ on the options they have to actually use it. Instead I am trying repin the gigabyte bracket and have it connect to this card. It does have DTS/Dolby decoding :D

So, the gigabyte manual says that the bracket has three pins.
1. red – Power
2. yellow – SPDIF_I
3. black – GND

So I switched black and yellow to match up with this pinout diagram of the creative card (top left, +5V, GRN, SPDIF0 IN)

Plugged that in and… nothing. I can hear feint popping when I switch audio output devices on the PS3, but the Creative card never shows a signal (“Unknown or invalid signal”, just like when disconnected).

Any help or insight would be appreciated, thanks.

P.S. I think I may have destroyed any input on my sound card by fooling around with this. My microphone no longer works on that sound card :(
