Question ATI video cards that output HDMI sound

I read somewhere that by some accident of design, certain ATI/AMD graphics chipset cards output sound through the HDMI port, that most other chipsets (namely nVidia) don't. Can someone point me towards specific chipsets?

I have a computer using the MSI Mother Board P45 Neo. The integrated sound chip is a Realtek ALC888 and sound is output through an HDMI connection to my TV.

The video card is a HIS HD 4670 IceQ 512 MB PCIe

It's not that other solutions can't output audio via their HDMI port -- just that they can't output 8-channel LPCM (uncompressed) audio via the HDMI port... and even that's a bit misleading.

Here's a good Anandtech article that explains what all this means.
