The boxes on Amazon aren’t that expensive and if you find one that works well 
enough you can run HDMI to the table, then terminate that HDMI at the box by 
the codec, where it’s broken out to DVI and audio, all hidden to the user

Ok. I’m more worried about laptops without a 1/8” speaker/headphone port or 
those with the dreaded combo headset port.

I think what I’ll end up doing (for proof of concept anyways) is getting a 
cheap USB-to-headphone+mic adapter and/or a headset-to-headphone+mic splitter 
and try those out. I’m thinking those should work very well.

The alternative, like you said, would be an active HDMI to DVI/audio out 
splitter that could be purchased by departments if required.

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

I’m quite certain it will not transfer digital audio from the HDMI port to the 
analog 3.5mm connector on the DVI side. That would require an active converter.

Given the complexities in this (and how it breaks HDCP) unless the thing you 
are buying specifically says it does it assume it does not.

Amazon has boxes that will do this, but a quick search doesn’t give me any 
cables that do it.

Does anyone know if the CAB-DVI-HDMI-8M+= cable will take audio directly from 
the HDMI source and pump it to the audio cable in the DVI end? Or whether both 
1/8” jacks need to be plugged in to feed audio to the far end?

We have a C60 and two SX20s that only have DVI in with a spare mic input. Of 
course, laptops nowadays have HDMI. Not too many have the audio out. Or close 
enough for that little pigtail.
