You could start by filling in your system specs (lower left corner) so we know what hardware you have.


thanks in advance

youre probably right, but this is one of four systems im now running and playing with win7 on.

its an old desktop pc.
i dont think it is the system thats causing problems though.
all drivers are okay and operating fine. the sound devices control centre is saying that speakers and audio devices are playing sound - the graphic equaliser is working, but no sound comes out at the other end.
i have just put a dvi to hdmi lead on to get both sound and vision in the same place on the tv, as when using a pci lead i could patch sound onto another channel using an rca lead adapter.
i just dont get what could stop the sound travelling down the same lead as the picture. lol

Well if you don't have a hd4xxx or geforce gt 2xx card you can't supply your TV with sound via adapter...
There is a tutorial how to enable sound on 8800gt and 9800gt:
Guide: 8800GT/9800GT/9800GTX Sound over HDMI (Now including Creative cards) - Overclock.net - Overclocking.net

EDIT: Someone did said that this doesn't work on 190.xx drivers

awesome, i will give that a try this week, looks plausable

I had a simular problem "AT FIRST" only to realise that with ONBOARD SOUND, You may need to UNPLUG your sound card connections to the speakers as you may have sensors to the connectors....

GO TO the SOUND control panel.... or select your volume control and chage its source to DIGITAL AUDIO HDMI - this will only appear after the tv is connected to the hdmi port... if your card is really good, you may have not noticed that the sound may have been coming out of "BOTH" SOURCES at the same time.....

If these options dont help just check your sound card driver again......If your running windows seven you should not really be having these problems really....

I have to agree with the OP here, Ken. The actual hardware being used on a specific OS has absolutely nothing to do with the problem.

Cross-referencing the OPs problem with a vast knowledge base of similar problems and solutions with known hardware would be absolutely pointless.

It is far better for you and I and other forum members to throw random guesses at a perceived problem.

 

[jfar]

I agree.

Is it me??? My understanding of the difference between HDMI and DVI is that DVI was the video element only of HDMI and that you needed to use another connection for AUDIO? Please shoot me if I'm wrong

I'm using the HDMI to DVI and a optic via SPDIF for Audio.

Some cards support HDMI audio over the DVI out - many require a low cost adapter between the DVI and HDMI cable.

A DVI to HDMI cable is not sufficient.

Example - ATI HD3850

I ask for that didn't I...lol

 

[benstevensuk]

all of those seem possible. i havent had a chance to play for a few days. when i have a proper look i will get back to you with specific graphics cards and what-not. i think this pc was (almost) hand built, so it could be almost anything.

just so you know, its not just the hdmi dvi cable that doesnt produce sound. i attached a headphone to phono rca cable adapter before buying the dvi cable. i could get sound, but only as a seperate source to vision, although that might be my tv picking things up and putting them in different places. my aim (obviously) is to get sound and picture on the same channel, preferably using the same leads. but since using the dvi out no sounds comes from the headphones jack either. i will check again.

cheers everyone

Cant be done, DVI is video signal only, HDMI is audio & video.

If your using DVI then you need to connect your sound card to your TV as well!!

Yes it can. See Antman's post on the 1st page of this thread. Any ATI card from the HD2xxx series and up, and most of the 9xxx series and up are all capbable of passing audio over the DVI connection. Only thing is it needs the adapter that comes with the card(s), any old DVI/HDMI adapter or cable won't work.

Also looks like we're still guessing as to what kind of hardware the OP is trying to make this all work on. Would help immensely if we knew if his video card, etc is even capable of passing audio over HDMI.

Gather your facts.

 

[Antman]

I've solved the problem, so why argue?
DVI can transmit sound and video and is HDCP compatible,...the only thing to do is to connect a 2-pin cable to your graphic card and sound card...
thread solved

No one is arguing. Plus, you solved a problem for a single card type and the solution is not the same for all card types.

What is being pointed out here is that a blanket statement, an incorrect blanket statement, will not survive scrutiny.

What you are seeing as an argument is simply an effort to prevent any additional occurrences of things like this:

True, but that doesn't mean someone should post xyz number of pages containing only message type "YOU ARE WRONG!"

I like small threads with simple solutions and not flame wars...

dvi connection to tv = no sound

Perhaps we are reading different threads. If only it was titled differently.

Sound via DVI

I can state categorically that on my system sound is provided on the computer DVI output. I have the DVI monitor socket on my Zotac GeForce 9300-ITX connected via a DVI-HDMI lead to one of the HDMI sockets (it does not matter which) on my LG 42LF7700 HDTV. On booting the computer the TV receives both video and sound over this connection, and a very good monitor it makes. The computer is running Windows 7 RC1, and I have a Hauppauge Nova-TD Stick dual DVB-T tuner plugged in to a USB port. Media Center provides both TV and music, which both work fine, until....
As soon as I switch the TV input from HDMI to either Satellite or Antenna (this TV has both types of tuner), and then back to HDMI again, the computer sound disappears. It can only be restored, it would appear, by rebooting the computer. Inconvenient to say the least.
The only clue I have found is that, in Control Panel/Sound/Playback, NVidia HDMI Out is indicated as 'unconnected' when computer sound is missing from the TV, whereas normally it shows as 'connected' and is the default device.
I have reloaded the NVidia drivers more than once, and in Device Manager both Nvidia and Realtek drivers show up as the best available. I can not think of anything else to try at the moment. All comments will be welcome.

No, sorry mate, but that simply cannot be. DVI connections do not carry sound signals. Period. Are you using a HDMI-DVI adapter?

Then perhaps you would care to explain how the sound signal is getting from the computer to the TV/Monitor. There is no other connection, and, no, I am not using an HDMI/DVI adaptor. Are you certain that the specification you cite applies to all the latest variants of DVI?
