Well it would be more accurate to say that HDMI without audio is DVI.
HDMI uses the same electrical signaling as DVI and is forwards and
backwards compatible as far as video goes. DVI also can support HDCP,
as this was necessary to watch Blu-Rays on PCs before HDMI connectors
became standard on video cards.

DisplayPort asupports both audio and HDCP, and even allows for audio-only
devices.  HDMI requires all devices to support video.  DisplayPort
uses a completely different signaling method than HDMI (and DVI) and
in general needs an active adapter to convert between the formats.
(Although DisplayPort optionally allows HDMI/DVI signaling to be used
in combination with much a cheaper passive adapter.)

If you're using Windows 7 (and I think Vista), right click on the
background of the Playback tab of the Sound control panel and enable
"Show Disconnected Devices".  They should show up then.

I think the "HD audio bus" is just a virtual creation of Windows to
group together devices based on the same Windows driver or driver model.
It dosn't represent an actual physical (or even logical) bus connecting
your NVIDIA and VIA HD audio devices together.

I'm not sure why you have 4 audio devices showing up on your video card.
My ATI card only has one.  It could simply be that it supports some
combination of 4 DisplayPort and HDMI devices all with seperate distinct
audio streams.

I wouldn't delete the drivers either.  Never know when you might connect
your video card to something that can use them.
