DVI actually can carry audio? :O

[Gachr]

Hi guys, today I experienced a miracle. I was using the integrated speakers on my monitor over HDMI, then I bought my headphones, I didn't need the speakers so I switched to a HDMI (monitor) - DVI (GPU) cable. I moved my headphones to another computer for a while, meanwhile I was sitting on my PC, and I hear Facebook notification sounds And sound works, how is it possible? I thought that DVI doesn't carry audio.

[flibberdipper]

It doesn't...

 

There's a reason it's called Digital Video Interface.

[Si3Rra_7]

Some GPUs do support audio through their DVI ports if they sense its going into an HDMI cable even though it wouldnt be supported over a DVI cable, i guess they have to get a bit creative with the sensing and wiring inside to get it done

[RelentlessAF]

There's two types, DVI-I and DVI-D one of them does carry audio. There are four extra pins used to carry audio.

The sounds are probably ringing in your head or the sounds are coming somewhere else, dvi doesn't carry audio(but it might work on some certain things)

Some video cards can output audio, but dvi monitors cant receive it. So it only works with some dvi to hdmi plugs.

DVI stands for Digital Visual Interface

DVI stands for Digital Visual Interface

So... It's a slightly different word, with basically the same meaning. :mellow:

Yep, I have the one with extra pins.

My monitor has got 2 HDMI inputs, I got an HDMI-DVI cable in the package, which I use.

[CowsGoRoar]

DVI-I has audio. The one with the 4 extra pins.

The graphics card will ignore the analog signal and read it as HDMI.

[vengeancek70]

I guess you got lucky with the combination of your video card and adapter.

No...

DVI-I can carry analog and digital signal, and the 4 pins are for analog. Can be used with an adapter to connect to a VGA monitor.

DVI-D only carries digital signal, and cannot be converted to VGA passively.

[Liam-McShane]

It will carry audio as long as it terminates as a HDMI to your TV.

[Deddie]

One of my monitors is connected with a DVI - HDMI adapter and I can get sound to the monitor too.

^ your right. also DVI-D and support 1440p or 1080p @144Hrz

[KyonCoraeL]

I was really surprised when I discovered that this actually worked when I tried this a few years ago on my older GTX280... I think that's what it was, lol.

[SirRoderick]

Key point is the HDMI here. If one end is an HDMI connector then the cable is wired for sound. DVI-I also does not carry a sound signal, but the connector can feasibly accept the signal into the cable with an HDMI connector on the other end.

That's dual-link.

No, that's not how it works.

DVI-D is digital

DVI-A is analogue

DVI-I is both

 

So either I or D will carry audio to the HDMI connector

A cannot because its analogue and cannot be passively converted to digital

[RelentlessAF]

It can do both buddy, the four extra pins are for the analog signal but DVI-I also transfers audio. Have used it to do so many times.

[RelentlessAF]

No, that's not how it works.

DVI-D is digital

DVI-A is analogue

DVI-I is both

 

So either I or D will carry audio to the HDMI connector

A cannot because its analogue and cannot be passively converted to digital

I have not been able to use a DVI-D for audio but have with DVI-I.

[Enderman]

I have not been able to use a DVI-D for audio but have with DVI-I.

Maybe because you have dual link DVI-I but single link DVI-D?

[RelentlessAF]

Maybe because you have dual link DVI-I but single link DVI-D?

It's possible, I lost the packaging for the both of them.
