first off wikipedia is not a reliable resource, though anything is possible. secondly this is not a problem with some dvi connectors this is the way the standard was designed, no where in the dvi standard is sound mentioned
Further the newest HDMI standards are capable of delivering higher resolution and color depth than any other connection, possible exception being display port but i don't think so. Of course in the real world we have no practical need for all that bandwidth just yet.
On jobs we use HDMI when ever we can, nothing can beat the pic quality and the sound is included with 5.1 channels. And switch to using coax to run component signals when we have to do long runs, bit of a pain to run 5 rg-6 cables to a monitor but it gives a great pic stereo sound and it's dirt cheap.
Alright, now after discussing it in here, and reading many opinions, I also bought the audio cable, since there was no luck with the HDMI to transmit sound.
I bought the standard cable: on one tip there is a single connection for the laptop, and on the other one there are two connections for the TV.
The problem is that I plugged the cables as it should be, and still; There was image but not sound. It can drive you crazy!
I read the TV's manual (Which is by the way Sony Bravia) and on one of the pages there was an image of the rear of the TV, with 2 inputs under the category of PC: one a VGA connection and one a common connection of audio.
I bought the DVI->HDMI adapter and the HDMI cable for more than 30$ and it's annoying when it doesn't work.
What can I possibly do, having the cables and tools that I have, just to remind: 1 DVI->HDMI adapter, 1 HDMI cable (1.5 meter long), 1 Analog audio to red&white (I don't remeber the name of the connection) connection.
I'm sure the laptopo doesn't have one of the graphic cards mentioned above.
The audio cable is indeed the standard 3.5 mm connection.
And about the second question: "have you got the correct sound device enabled in windows?" I'm not sure, I played a little bit with the sound settings while being connected to the TV but with no success.
Are there any other setting or options that I can adjust?
If you get sound out then I wonder why it is not working. If the TV has an audio in using red and white RCA connectors then I would think it would work fine.
Seeing as I had the equipment handy I decied to test this out using an old laptop I had. Connected it up using a dvi to hdmi adapter and connected to a tv using a 3.5mm to red and white rca connectors and the picture and sound worked fine.
There must be something that is stopping it from working. Does anything appear to be muted or the sound turned down very low perhaps. Unfortunately I am not sure what to do next.
I went to the store and they told me what we are talking about for the last days, that there is no reason for it not to work. They even showed me how to connect it (the audio cable) using one of the TVs that were there. There was no need of showing, because they did the same that I did.
Anyway, I took the same cable back home, to see if I can try another entrance or setting in the menu.
I will go tomorrow to Sony's representative and see what they can advise me.
