SPDIF output and USB external sound card

[GAINELL]

I have a USB external sound card (M-Audio Audiophile), it has a SPDIF input / RCA. My motherboard (based on nForce2) has a SPDIF output / RCA. I try to connect my SPDIF output of my motherboard in the SPDIF input of my sound card. I am facing the problem is that I can have a single application that uses the sound device. I tried with jack indicating that it must use the SPDIF output of the nForce2.

1. Disable the onboard sound card in bios
2. connect the USB it should logically be seen as the only.

Assuming that this is your model (because you do not mark the site and the series) must eventually settle the case to activate the inputs / outputs that interest you.

If not then you have to share your audio on your desk rather than behind the PC I do not see what it bring you more than the nforce?
Whether you prefer the audio quality of your USB, use the Nforce to transmit information is stupid, because you will degrade the signal in the nforce chip will not be improved then

If you really want to inject the spdif output on the contrary spdif not and neither does sound cards resampling internally then you can try something. Indeed, a sound card and normally do not consist of internal re-sampling will synchronize on the incoming stream. And as what is between what sort of other sound card sync the two is guaranteed.
