Default Re: SPDIF Out on X-Fi to SPDIF In on nVidia cards

Like LovingSticky, I can hear only Stereo output. I tried to format PC, installing XP and latest version of the X-Fi driver but no news on the topic.
In the next days i want to test using KMPlayer and YPax driver. In case of success I'll update you.

Frankly speaking, I'm not sure if problem is hardware or software. Does anyone have an update on this topic?

Have you tried disabling the internal decoder on the X-Fi ( if you have one) and playing back a DVD or something with the DVD Player set to SPDIF output? Unless your player is outputting a SPDIF signal you'll only get stereo out of it.

if you have an X-Fi you should be able to get the Dolby Digital Live/DTS connect pack to generate a DD/DTS signal in real time for SPDIF output for all audio from the PC.
