Are you sure your default audio device is still "speakers" and not the optical out? Every time I install the drivers, I need to check that for sound to go out over optical unless the SPDIF optical out is the default audio device.
The SBX Studio effects are only on the "speakers" device. The SPDIF optical out device is a 2-channel only without any effects.
There must be an internal routing from the "speakers" device to the "optical" device to get the SBX effects to go out over the optical port. That's what that option does.
