790, No Display Port ++ audio signal

According to what I find doing a internet search, Display port does not contain audio.  Converting it to HDMI will only supply video.

The 790 does not come with Display Port Plus Plus ports.

The audio codec in display port is optional.

That's why the 790 doesn't sport the plus plus logo.

There are no audio signals on DVI

So DVI to HDMI is video only.

Display port Plus Plus to HDMI will only supply audio if the attached device has the PLUS PLUS ports on it.

Display Port Plus Plus

DP++ has audio signaling for adapters. Display port doesnt do audio but has and audio pinout for HDMI adapters to carry it. I have a DVI adapter that supports this audio pass-threw as I get audio via my Ubuntu partition. 

I have Ubuntu 16.04 installed and it picks up audio just fine. Like it plays threw the display port. It says "HDMI Emulated Audio". I got this very same thing in windows 10 but never got it again after the first boot. 

"DVI adapter that supports this audio pass-threw as I get audio via my Ubuntu partition"

DVI has NO AUDIO Signals. 

DVI has no audio

"If you want to transmit audio over DVI, you’ll need to use a special DVI-to-HDMI cable (or adapter) Assuming your computer’s video card supports HDMI audio via DVI, this cable will allow you to transmit both video and audio using a single cable. The good news is that most modern video cards support this feature. If you have an older video card, however, you may have to upgrade it."

This is true as again, I got audio threw DP ++- > DVI D - >HDMI. It has the support because it works in Ubuntu currently. I'm listening to music on my TV in Linux 

I'm trying to see if someone has a fix or something to correct it. It could be a windows problem but as I said, it worked initially and after the first reboot it wouldn't even detect it. I've done another clean install and it doesn't find it anymore.

There are NO AUDIO Signals of any kind on DVI.  Never have been Never will be.  There is no correcting that which does not exist.

Display port Plus Plus to HDMI has audio ONLY when the output port on the machine is PLUS PLUS.

PLUS PLUS OUTPUT is optional

 dvi - A pinout

Did you not read anything I have posted? It is a ++ port on the computer. I have audio right now via DP>DVI>HDMI, that works fine as long as I am in Ubuntu. I posted pictures so you can see that, you can see where it says "HDMI/Displayport". Stop replying if you're just trying to make yourself sound smart and punch holes in my question, I have a CompTIA A+. I know what I'm talking about.

DP++ to DVI  has no audio signal to pass to HDMI.  There are no pins on DVI defined as carrying audio signals.

DP++  directly to HDMI can have audio.

DP++ >>>>> DVI  >>>>HDMI does not have a path for audio.

You may have an internal speaker that audio is going thru but this is not related in any way to an external monitor.  The Adapter below is DP++ directly to HDMI and would have audio EXCEPT if the port its plugged into is not ++ then it still wont work.  I do not see the ++ logo on the 790 case nor do I see the audio codec mentioned in the specifications.

Ironically, I installed Win11 and it "Just werks"

It now lives as a Sophos Firewall haha

Just following up as I also had this driver "bug". The default Intel drivers do not pass on the audio with the DP++ onboard and a i7-2600. I had even checked using chrome and the intel (R) driver and support assistant and it said no updates were available for the any drivers. Dell claims not to support Windows (R) 10 on this PC. I found the windows 64 bit 8.1 drivers from dell to work and pass the audio down a DP++ to HDMI cable adaptor. Dell labels this driver: Video_Driver_W74GJ_WN_9.17.10.3517_A15 Additionally for those whom may be troubleshooting adaptors ubuntu 22.04 iso can be run live and will test the adaptors. I had issues testing my hardware with the newest knoppix.

Apparently there was an undocumented DVI to HDMI with audio hack that many vendors went along with. 

This specific adapter does pass audio via DVI because its single link and uses the middle pins to pass the audio.

You Add a DVI to HDMI Dongle and get the best of both worlds as far as digital but you do not get DVI-A  analog because the other pins are not passed thru.

I have tested this with a 790 and 990 and it works fine for both video and audio windows 10 or 11.
