HDMI vs DVI

Other than a big difference in connectors, what are the differences between
DVI and HDMI?

I (incorrectly?) understood that DVI does NOT carry digital audio, where
HDMI does. Is this true?

DVI does not carry audio, HDMI does.

HDMI is capable of larger color spaces, but many (most?) current sources and
displays are not able to use them. Both HDMI and DVI are capable of carrying
the bandwidth required for all HD signals.

Typically, with current gear, HDMI is a superset of DVI. That is: a DVI-HDMI
adapter cable just maps pins on one end to pins on the other. I use one and it
works well.

Receiving cross signals (np pun here). I was unclear:

If my SOURCE is HDMI and I use an HDMI-to-DVI adapter, then a DVI-extender,
then back to HDMI, then I will see audio (??)

If my SOURCE is DVI, I will NOT see audio. Understood.

HDMI HDMI DVI adapter DVI Extender DVIHDMI adapter HDMI, then

Yes and that is the difference between the two.

I very much doubt it. The DVI adapter will have nothing on the DVI
side to connect the audio signal on the HDMI side to. So all this
connecting would get you a video signal, but no audio.

No audio, seen or heard, in either case. No pins for it.
