DVI to HDMI equals NO sound!

It's HDMI on the card and DVI on the monitor? HDMI normally hijacks the sound. I've had that issue too. DVI can't carry sound, which is a huge pain. HDMI is basically a DVI + audio cable.
Card has output for VGA, DVI and HDMI
nVidia has DVI audio in their control panel software

Contacted Best Buy Geek Squad and they were impressed that I figured it out as they would have suggested sending it back to Asus.

I wish I had a screenshot for you that shows the Audio tab with the DVI chosen to provide sound, but I will get one next time I am at the clients office.

DVI Audio? That's weird. I wonder how they are doing that.
-
@scottalanmiller I thought it was weird too.
-
I wonder if they are doing something proprietary or if there is a new standard that I don't know about (I don't keep up on DVI that much) or if they are mislabeling HDMI? I'm a little confused.

Can you clarify the connections? You said it's DVI to HDMI but then you said it's DVI at both ends.

Customer bought 2 new Asus M51AD PCs with nVidia Geforce GTX 750 1GB cards from Best Buy which came with HDMI capable monitors (one 24" and one 27"). So when the customer setup the PCs she used the DVI to HDMI connector. DVI out from video card to DVI on monitor. W8.1 PC
So, which end has the HDMI, the monitor or the computer?
-
Here it is... apparently there is a means of putting audio onto the DVI cable so that when you convert to HDMI it is there. Basically, I think, they are bastardizing the DVI standard to make this work.

HDMI to DVI generally will be either one cable for video and the sound just dies after it starts going into the HDMI to DVI cable, or the DVI connection has a secondary connection for audio, usually a 3.5mm jack attached to the DVI cable with a little slack. Which do you have?

Fixed: DVI out from video card to HDVI on monitor.

Ok, this is weird. I could see issues if you were doing it the other way around, but the card shouldn't have audio capabilities. The cable is its own thing. Can you get a screenshot of the Audio devices/sound devices in Device Manager?

I had read about that a while back...so by connecting the cord from DVI to HDMI, why would I lose all sound? Was it the connection via 3.5mm jack?
-
@technobabble The DVI actually carries the audio. The system is basically using the DVI connector as an HDMI connector. So it sees an audio device plugged in.
We've solve the mystery of why it wants to do it. Now the mystery is, why does turning it off on the card not turn it off?

I don't have it but I can tell you that both the nVidia manager software had DVI set to auto and under Sound in the device manager where was nVidia listings for sound. drivers
-
The nVidia driver could see the connection and kill the sound.

Thanks @scottalanmiller for bringing the discussion back on track...this is what I has hoping to find out!

I bet it was that auto setting. What were the manual choices?

You said you DISABLED the device under Windows Sound Playback Devices?

@Dashrender I thought that too, but if I disabled the drivers in Devices manager and disabled in nVidia software no sound occured. How is that? Freaky...

I'm seeing a weird problem like that right this second..
all of my normal sounds are coming out of my plugged in speakers, but for whatever reason, the webinar I'm watching is coming out of the internal HP speaker (hard to hear).
