I forgot to mention that to hear surround sound in your audio system, you have to set up the computer to 2.0 channel output. Then your receiver's DPII decoder will do the rest of the work, just like it would with the actual console. This is one of the last few things I wish could be done reliably in dolphin without the LLE overhead.
