Creative X-Fi Surround USB -- spdif - only front speakers

I am running opensuse 11.1 and trying to use the SB1090
(Creative X-Fi Surround USB sound “card”). I receive
sound through the front speakers at boot and shutdown,
the speaker test works for left and right front. The test
on Yast never works. I have defined the card as generic
and usb, the on bound sound (Nvidia) has been disabled.
The only sound card is the USB, which is card zero, with
USB and USB AUX. The alsamixer only shows a master volume
and capture columns, the master is not muted and set to 81. The device on card 0 for iec958 is 0.

When using VLC, if I change to A52/SPDIF, nothing is
heard. If I remove the check in the audio set up, then
the sound works, but only for the front speakers, and no
indication on the receiver (Sony) of 5.1. The X-Fi and
the receiver are connected by optical, with no speakers
attached to the X-Fi at all.

With aplay I can play a ac3 file with the plughw:0,0
setting, but it still is just the front speakers. I
looked all over the web and have found no solution.
Suggestions are welcome. tia.



No one has any suggestions?
