I think it's required for HDCP content protection so that the audio path over HDMI is secured.

Makes sense but you certainly don't need the MOBO sound card if you have a USB or PCI interface. I always disabled it in my main PC running a 2496. I leave is working in this W7 HP laptop because I can then record radio sound (stereo mix) and it is convenient to just plug cans in. The drivers in my KA6 are good enough that they just overrule it, not all might?

This is not the Mobo sound chip but one built into the graphics card which in this case was highlighted as being an AMD card.
I think the main purpose for it is for content protection purposes.
They want a secure path from the PC to a TV so that you can't rip the raw audio data stream.

It's useful when for example you connect a laptop to a TV, provided it's selected, otherwise you would get no audio passed to the TV over HDMI.
This is my limited understanding of the situation and I imagine there's more to it than this.

Yes, HDMI sound. THAT is what I said made sense but there is always, AFAIK, another soundcard on the MOBO. In fact I have an Asus MOBO that does not even have graphics! Hissed me off when I realized, had to shoot to Maplin and spend another 30 quid. Oh! Those were the days!

We were talking about the HDMI audio chip on a Graphics Card though so different topic.

No? OneWorld asked if he needed three "soundcards" or just his RME.

That was the bigger picture but I only responded and quoted him on the Graphics card chip hence that was the context of my engagement.

ALWAYS thinking of the bigger picture friend!
