I'm not sure if this helps.
But i was facing this issue with my HD3 series as well a while ago.
There was a Microsoft High Definition Audio Codec or something which needs to be installed to get rid of the message.
I've faced this issue with all 3 of my gigabyte motherboards and all solved after installing the thing mentioned.

By right, if the audio thing is built-into the GC, you should be able to get the driver from the GC manufacturer.
The Realtek driver is for the integrated Audio chip on the motherboard, so even if you try to install the Realtek driver it is not looking at the GC area, it only looks at the motherboard.
The drive CD comes with the GC doesn't have the audio driver, only display driver. I also went to their website and downloaded Catalyst 8.12 and installed it. On Realtek site, there's a driver for HDMI audio, that's for the audio chip on GC. My audio on motherboard work fine except when I use Line Out or Headphone out to TV, it has lots of static. It's really annoying. That's why I want the HDMI to work. Motherboard also has S/PDIF out but my TV doesn't have S/PDIF in, I don't think. Besides even if it does, it won't be in the same input port as image from PC by either DVI->HDMI or RGB.

I'll look for it on Google. Thank you.
Added on December 30, 2008, 3:08 amI just got a response on my ticket from ATI. The Microsoft HD audio drive I need is UAA driver. It's only needed for XP SP2 or earlier. I am running XP SP2 so I need that. Vista has that already. I'll try that when I get home and give update here.

After I installed UAA driver, the system immediately recognized the "new hardware". After I installed the HDMI audio driver from ATI website, restarted system and everything works fine. I now only use one HDMI cable connecting my computer to TV and have both image and sound.

Just for future reference, in case some one else is also having the same problem, here's the link AMD provided me:
