[cisco-voip] cisco hdmi to dvi cable - audio from HDMI?

[Dave Goodwin]

I don't do this stuff very much but I think yes, pretty much. The only time
I've recently piped my PC video AND audio to the room system was when I
just was using it as a huge monitor to play a video with sound for people
in the room. Maybe others actually have a use case for playing video with
sound into a conference through the presentation cable, but that's not how
I'd want to do it. I'd rather use some kind of client that supports sharing
to dial into the meeting from the PC itself. Jabber is one option, maybe
Cisco Meeting App is another (I don't use it, so not sure), there are
probably others. Also, I seem to remember that playing full motion video
doesn't always look that great without tweaking my config - some systems or
apps I've used in the past default to limiting the presentation layer to
15fps.
