DVI -- no audio
HDMI -- audio

"Type A HDMI is backward-compatible with the single-link Digital Visual
Interface carrying digital video (DVI-D or DVI-I, but not DVI-A) used on
modern computer monitors and graphics cards. This means that a DVI-D
source can drive an HDMI monitor, or vice versa, by means of a suitable
adapter or cable, but the audio and remote control features of HDMI will
not be available. Additionally, without support for High-Bandwidth
Digital Content Protection (HDCP) on the display, the signal source may
prevent the end user from viewing or especially copying certain
restricted content. (While all HDMI displays currently support HDCP,
most DVI PC-style displays do not.) Type B HDMI is similarly
backward-compatible with dual-link DVI."

Thanks for clearing that up Lem. : )

You're welcome.

Of course, there was a story in this morning's NY Times about why you
shouldn't rely on Wikipedia articles:
A History Department Bans Citing Wikipedia as a Research Source
http://www.nytimes.com/2007/02/21/education/21wikipedia.html?_r=1&oref=slogin

But I think in the case of HDMI/DVI, it's pretty accurate.
