I have a GTX 760 and just got a new ASUS VS2484 1080p monitor with HDMI in and speakers. So I got an HDMI cable instead of using the DVI I used for the previous monitor.
 
After some false starts, got the HDMI video signal to work. Verified the audio is enabled and the monitor volume up.
Yet no audio.
 
I tried the instructions here:
(hey, my link got deleted - it was the 760 manual)
and here:
(also deleted! That's helpful. It was the EVGA FAQ 'how to enable HDMI audio')
 
and enabled the HDMI Audio device, which is recognized and displays as:
VS248-4
NVIDIA High definition Audio
(checked) Default Device
 
Audio's not muted.
 
Nothing.
 
Restarted PC from power off, uninstalled NVIDIA drivers, did a clean install of the latest driver, verified everything's enabled again...
 
Nothing.
 
One thing I notice different between the instructions and what I get onscreen is this:
(This was the screenshot of the NVIDIA control panel here link copied from the EVGA faq linked above)
The screenshot shows "Connector" having two choices - Audio Enabled and Audio Disabled.
 
I don't get that. I get one choice.
Connector - HDMI-HDTV (no dropdown, no choices)
 
Anyone have any ideas why I can't get sound? I don't even know how good the speakers in the monitor are, but I at least want to hear them. They would be more convenient than the external analog ones I have.

I can see the monitor as an audio device. I can select it. I just get no audio.
And in the NVIDIA control panel, I get only the connection "Connector - HDMI-HDTV" not two versions with Audio Enabled and Audio Disabled.
 
When I did a total uninstall and clean install of the drivers, I did a Custom Install with all options, including the audio driver.
 
I can see the monitor listed:
VS248-4
NVIDIA High definition Audio
(checked) Default Device

Hmm....does it even have built in speakers?

Well, crap. It's got a built in volume control for the monitor, but to actually use the HDMI Audio you have to CONNECT HEADPHONES OR SPEAKERS TO A JACK IN THE BACK OF IT.Asus wasn't clear on that in the manual, it just said the headphone jack only works when HDMI is plugged in (which of course makes sense, otherwise how is audio getting to the device?).
 
I guess I assumed that since it had HDMI audio acceptance and a headphone jack it had speakers.
 
Totally my bad guys. Thanks!
