Hi I'm after solutions to achieve audio pass through under Windows

Basically I bought a cheap Creative USB sound card which has optical input enabled.

I want to pass the digital audio from optical input to my BOSE C5

Is it possible

Thanks a lot Regards RW

Optical output on Windows complies with the SPDIF standard which means that it can carry mono, stereo, AC3 (Dolby Digital), or DTS. It cannot carry LPCM which is necessary for unencoded multichannel playback.

So, while you can hook your PC up to an external receiver via optical you will only be able to play sound from stereo sources or AC3/DTS sources. Multichannel sources such as those found in most games will not work unless you use a real time Dolby Digital encoder. Creative makes this function available on a few of their high end sound cards.
