Audio working but still exclamation mark

I've just installed XP and installed all the drivers. The Realtek audio driver seemed to install fine - 'proven' by the fact that audio works - but in Device Manager, there's still yellow exclamation mark against 'other devices', 'audio device on high definition bus' and 'unknown device'. When I boot, the 'found new hardware' wizard appears. It's a minor annoyance - but I'd still appreciate any thoughts on how to fix it. My initial thought is that it may be something to do with the Intel chipset drivers not having loaded properly, but I don't want to miss with them if I don't have to.

I think that you may need the AMD Catalyst Software Suite which includes the AMD HDMI Audio Driver. Download from AMD AMD Download. If the link doesn't work too well then go to AMD Downloads and select the various options eg Desktop graphics, Radeon HD series, Radeom HD 6xxx series, Windows XP.

Thanks Woolwell. That's the driver I've installed... :-( The mystery deepens.

So... Further investigation found me here. I note that there is a recent release (2.70) of the Realtek driver (the one I've installed looks like it dates from 2010). I also note that there is a driver specifically called 'ATI HDMI Audio Device'. I'm intrigued, because other research I've done tells me that, if the Realtek HD audio driver were 'properly' installed, when I go to control panel/sounds and audio devices/audio, there should be an alternative default device listed. So, my quandary is, do I a) install the new driver, even though it's not strictly the one for my mobo (Realtek point out that there's a is a generic driver), b) install the ATI HDMI Audio Device driver, or c) leave well alone before I break something...?
