Whether it works or not with a random laptop I can't say.  I'd wager

Good question Eric.  Searching around it seems very hard to identify which nvidia GPU's have the digital audio combining 
capabilities.  It seems it may be more an option implemeneted by some manufacturers and not others?  Does anyone know if the 
nvidia-settings acknowledges the spdif passthrough when its present on the graphics card?  (I don't have one setup to check)


from the above reference:

DVI is mostly compatible with HDMI. The main difference is that DVI typically carries no audio data in its TMDS channel, although 
increasingly, modern PC video hardware is providing audio (e.g., cards by NVIDIA[2] and ATI[3]), allowing the PC to send audiovisual 
data to a high definition television with an HDMI input. If a PC's DVI output does not provide audio, it can be patched in as part 
of the DVI to HDMI adapter."

If the Dell D830 does not output the spdif over DVI, (I expect Eric is probably correct) then one of these would likely work:

from the Docking station.  Sorry I haven't tested this though.
