got it working finally YAY, but only thing is there is no sound when using chrome launcher to launch chrome :/ however there is sound when on desktop so, time to find a fix

I had the same problem and found that XBMC was "holding" on to the sound output while it is open. Try going into the system settings, sounds, and change "keep sound alive" from whatever it is set to, to 0. This worked for me using hdmi output to an Onkyo receiver. I hope it helps you because it took me a few weeks to figure out why silverlight kept throwing up audio errors when loading Netflix.
