• Audio from DVI to HDMI ?
    9 replies, posted
Got a problem here, fellow facepunchers. I read that it is possible to output sound from my Radeon 4850 graphics card, I have a DVI to HDMI adapter attached to it, and a HDMI cable going to a tv. I tried to search from the Catalyst Control Center but couldn't find anything related to audio. How do I enable audio output to my TV? I think it is possible with my card.
Where did you read this? DVI cannot output an audio signal, only video.
Actually I got it to work. Here's what I had to do, very simple [img]http://i.imgur.com/KJDSy.jpg[/img]
i learned something new today.

That makes sense.
[QUOTE=MorningWoody;33509674]Where did you read this? DVI cannot output an audio signal, only video.[/QUOTE] My understanding is that DVI carries audio, but only in the sense that it can hand it off to HDMI through a common adapter. I don't know of any devices that accept audio video DVI.
DVI can run audio signal but it isnt used in that area, in the same way a BNC cable can run audio but it is commonly used for professional video purposes. HDMI was [I]made[/I] to carry audio and video, which is partly why its so expensive. BNC cables are inexpensive but are extremely shitty when used with audio feeds for some reason. At my school, where I am in charge of the Technical Service group, of whom runs all audio visual and performance aspects of the schools own TV network; we use BNCs to carry video and 1/4" Line cables and XLRs for audio. I have experimented with combined with single-cable audio and video on a BNC and the result was fucking catastrophic
I believe it's a proprietary converter that some videocards use to deliver audio through the DVI to HDMI converter with pins that are usually unused (the ones for DVI-A when you're in DVI-D mode are unused).
