Here's what I've got

Compaq Evo N800c with docking station (has digital Coax out)
Computer uses SoundMax digital audio
USB HD
Harmon/Kardon Receiver

I have the laptop connected to the receiver using the digital coax output on the docking station. I was wondering if there was a way to force fb2k to output only through the spdif. Otherwise, I have to mute my computer (if I wanted it coming out my laptop speakers, I wouldn't have hooked it up to my receiver!). If possible, I'd like to take it a step further and get system sounds to output only through the speakers.
