Enabling Audio Options on the NUC

More questions about my ROK/NUC install. Clicking on the “Audio” link in the Set-up menu reveals a lot of things that I cold enable on the NUC. The HDMI options are particularly confusing to me because there are 5 things to enable, but I’m pretty sure the NUC only has only 1 HDMI output. I also don’t what the what HDA Intel PCH ALC233 Analog is.

I guess main question is: what would enabling these things do?

See this thread:

The Analog device is for the audio output via the 3.5 mm jack socket.

HDMI 0 appears to be the physical HDMI output (or at least this is the case with my 717BNH NUC). I have this connected to my AVR for some surround format stuff I was trying out.


Go into the bios and disable the sound card and they go away.
