SPDIF Output to Amp

[WarpedMonkey]

Ok here is my setup:
- My SPDIF Output looks like a normal headphone jack (http://www.xoticpc.com/laptop/9280/92805.jpg)
- A40 MixAmp, which I can connect to with either RCA (Red and White) or Coax (Orange) or TOSLink.
- A pair of Sennheiser HD555

My computer doesn't have Coax as a digital output nor TOSLink, so I'm left with this weird SPDIF Output.

I've tried putting a 3.5mm stereo plug to Red and white. It works in the headphone jack, but not in the SPDIF output. All I get is weird sounds and hissing. (I did change my computer settings so it uses the digital output). All I could find on the internet was that I needed a mono jack instead of a stereo jack. First, I don't know if it's true and second I can't find any cable 3.5mm mono male to RCA male.

Any help would be greatly appreciated.

Thanks in advance,
WarpedMonkey

The output is digital, so you need a DAC.

B) Toslink Optical Digital - (cable not included) Connecting to the MixAmp’s™ rear OPTICAL input: Many PC motherboards and sound cards come standard with an optical (Toslink) digital output. You may need to adjust your PC’s Audio Properties, and enable Digital output (with XP, this is usually a check box). Consult your motherboard or soundcard user manual for further information.

I think the MixAmp can decode digital or analog.

This looks like it could really be working!!! I'll try to get those cables tomorrow and post my outcome. Thank you
