The sound driver justneeds to set up it.Of course, there must be a big difference in the graphic hardwareimplementation. But it's all about the graphic driver and the sounddriver can't do anything. Note that some devices (mostly some old machines before Nvidia MCPHDMI came out) have special setups. They hook the SPDIF pin ofanother codec into the graphic side. > But, well... it might just work.

The situation is basically same for ATI, Intel and others.
