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

@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?
Thanks @scottalanmiller for bringing the discussion back on track...this is what I has hoping to find out!
You said you DISABLED the device under Windows Sound Playback Devices?

@Dashrender said:
The nVidia driver could see the connection and kill the sound.
@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).

@thanksaj
- I checked nVidia's software and there was a DVI audio link, so I disabled it.
- Disabled nVidia drivers in the device manager under Sound

Yes
I really should have speakers on my work PC...I haven't had sound since since 2011 on my W7 PC. I mean I have earbuds connected for occasional music or webinar. I am usually surprised at the noises Windows makes when onsite with a clients PC.
-
That's odd. I have speakers on and I don't think that my Windows makes any sounds.

If it's using Webex or GoTo Meeting, it could be a presentation setting, like something you'd set in Skype.
-
Yeah I looked through those presentation settings, so far no changes.
-
Ok, I just thought of something really obvious. Enable the device for the DVI link, and turn up the volume on the monitor. Do you get sound?

That's the only thing that makes sense. Really weird...

Yes. That was for you. We need to establish if in the process of killing sound from the speakers if the sound even works from the DVI to HDMI in the first place.

No sound at all when DVI to HDMI was connected.

The sound would have been routing through the monitor. Was the volume up on the monitor?

Yes the volume was up. The sound works though the monitor speakers if connected via 3.5mm jack and VGA cord.

I was more looking to see if it worked with the adapter itself. I wonder if there is an issue with the adapter.
