Just picked up the Phoebus card, and it is connected into a 5.1 channel system (not using digital thus far.) Running Windows 7 Ultimate with 8GB of RAM. I do have the card set in the control panel for 5.1 operation, but only the front/left and front/right speakers work when I try to test them from the control panel.

If I go into the Phoebus app, I get the same thing - clicking those speakers results in the "Front left" voice. Clicking the centre channel I end up with something muffled and very faint (regardless of how high the volume is set.) I've looked through everything I can think of, and I've verified that all the cable connections are done properly.

Anyone have any suggestions ?

Thanks.
