Radeon 5450 won't play audio thru HDMI

[spin498]

I have just done a fresh install of Win 7 Pro on my HP. I am giving the machine to my son so did a complete wipe and installed from scratch. I've got a Radeon 5450 video card and downloaded the latest drivers.The AMD HD audio shows up in my device manager as properly installed. But when I try to configure it I get the 'this device is being used by another application'. Task Manager shows NO other apps running and I ran Msconfig to stop the two programs loading at start that came installed with Catalyst. No joy.

I would note that it all worked fine on my old installation that i wiped.

It's the only sound device listed and it's set as enabled.
