I have lcd tv with hdmi input and you are meant to be able to use analog audio but the problem is the video card has dvi output only.
But when you use an adapter the tv gets a false signal so it cuts off the analog connection
ive just wasted alot of time finding a solution so thought i would share it
its not mine i found it on the net
first you need to download moninfo.exe
heres a link but you can just google it

Part III - Spoofing the EDID signature
If none of the measures described above helped you to get your screen picture and analog audio the way you want them to look and sound, it's time to resort to EDID spoofing. Also, if you are an experienced Windows XP / Vista / 7 user, it should be easier for you to fiddle with the registry than with the cables and adapters.
EDID spoofing means that you are about to deceive your graphics card into thinking that your TV panel uses only DVI connection and has no HDMI capability. You may get some of your display settings screwn. Or not. Really depends on the system, but more often you get away with it than not. There's always a way to undo the changes.
Here's the instruction (don't ask me why it should be done this way and not another - it just works and that's ok).
The instructions below are given for Windows XP 64-bit, but there's little difference between its registry structure and what you'll see in Vista / Win7.
1. Shut down the system, disconnect all the displays except the TV panel (use a digital connection: DVI->HDMI, DVI->DVI or HDMI->DVI)
2. Boot up and get the Monitor Asset Manager: [LINK]
3. Run it and look into the upper left window as seen in the picture: [LINK]
4. One of the entries should be marked as 'real-time', not 'registry'. That's the display that you are currently using. Select it.
5. In the 'Raw Data' window, copy the first four bytes (symbol pairs) from the second row, as seen in the picture: [LINK]
6. Now it's time to make up the magic spell. Paste these symbol pairs, e.g. 4C 2D C4 03 in a text document. Then add the following symbols: 00 00 FF FF 04 00 00 00 7E 01 00. In my case, the spell looks like 4C 2D C4 03 00 00 FF FF 04 00 00 00 7E 01 00. Obviously, the first four bytes (shown in red) will vary depending on the model of your TV panel.
7. Press Start, choose Run, type Regedit and press enter. Here you go, you're in Windows Registry.
8. Let's see where Nvidia graphics adapter settings are stored. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\
9. Inside \Video\ you will see one or more folders named like {########-####-####-####-############}. Each folder corresponds to a different GPU found in your system. Cards with 2 GPUs will get you two folders per card, the same goes to SLI setups. So a triple-SLI setup of GTX 295 cards should result in six different folders there.
10. It's hard to tell which folder corresponds to the GPU that actually drives your TV panel if there are two or more folders there. So let's make each and every GPU forget to use HDMI connection with this particular type of display and emulate a DVI link instead. None other displays will be affected as long as they are of a different model. And if they are of the same model, you'd want to fix the missing analog audio for them, too. (Honestly, I can hardly image a guy with two or three widescreen TVs hooked to the same PC in the same room)
11. Inside each folder named like {########-####-####-####-############} you will see a folder titled 0000. Open it and behold a crap load of application-specific parameters. Scroll the list to the very bottom, right-click on it and do Edit / New / Binary Value. You'll get an empty binary value at the bottom of the long list.
12. Rename the New Binary Value into OverrideEdidFlags0 (no typos please or won't work!). Right-click on it and choose Edit Binary Value. In the opened window, type your spell, e.g. 4C 2D C4 03 00 00 FF FF 04 00 00 00 7E 01 00. That's how it likes when if done properly: [LINK]
13. Apply the same procedure to each folder titled like {########-####-####-####-############} inside \Video\
14. Reboot and enjoy your analog audio
15. If the analog sound isn't back, send for the witch doctor. But most likely you did something wrong - misspelled the spell or tinkered in a wrong registry folder.
16. To undo the changes simply kill all these newly created OverrideEdidFlags0 parameters and reboot.
17. If you lose your analog audio again after reinstalling or updating video drivers, repeat the whole ritual.
