the title is basically it. i have a p5w dh deluxe and the spdif coax broke and since coax is wired already and toslink was not i replaced it with this: http://www.newegg.com/Product/Product.aspx?Item=N82E16829111001 because of the newegg reviews that said it was a cheap 'spdif passthrough' and tonight i connect it and my reciever and this software is only outputting 2 channels? what the poop? i want my reciever to do the decoding but dts doesnt even work in this 2 channel mode. should i have gotten something else and return this? or am i doing something wrong? thanks for your help

The only way for SPDIF to transmit more then 2.0 PCM is by using Dolby Digital/DTS (which are both compressed enough to fit over a SPDIF connection). For PC audio, the only way to make a 5.1 stream with these formats are using two methods known as Dolby Digital Live (makes audio a 5.1 Dolby Digital stream) and DTS-Connect (makes audio a 5.1 DTS Stream). If you lack these two methods, you're PC is stuck at 2.0 PCM while using SPDIF.

That being said, you should be able to pass through audio that is already encoded without any problems.
