Hi, not sure if this is the right place to ask this, but here goes:

I've spent hours and hours browsing sites and forums hoping for a solution, and keep thinking im on to something, but still no luck. I've noticedd a lot of good responses from this site, so hope for a bit of luck :D 

I'm attemping to hook my LG LCD TV to my PC (with windows xp 32-bit). I've attempted dvi to HDMI cable with seperate audio cable, and now moved on to HDMI to HDMI cable (using supplied dvi-hdmi dongle that came with gfx card).

However, I can only manage to get picture and no audio. I'm using GTX 280 and a Asus P5Q Pro, which i've connected using a SPDIF connection. I've set output to HDMI audio in the BIOS, but still nothing & in my Realtek Audio Control Panel the digital output bit is greyed out.

The bit I belive is the problem (tried countless solutions) is that in sounds & audio, the only device is Realtek Audio Output, i cannot select HDMI, or SPDIF (they don't appear at all).

I have latest drivers for nvidia graphics card + realtek audio drivers.

Going crazy here, nothings seem to work. Appreciate if anybody can help

Thanks, Sharpey

Okay, so, I'm so not even close to computer savvy but I had the same issue with my TV/PC hook up. Nothing I did with HDMI cables worked at all. My TV came with a VGA hook up on the back which is what I ended up having to use. But after all the nonsense with the HDMI cables my realtek had put digital audio as my default so I had to go back in, hook up normal speakers and set the speaker setting as the default before I could hook up the audio to the TV...

But of course I had to spend an additional $30 on those cords... I hope this helps, and I'd like to know if you ever figure out the HDMI cable thing because it would save cable room behind my TV, lol.

Maybe you have seen this already but Nvidia has a fairly detailed answer regarding no audio output....maybe it will help.

hmm, the URL is obnoxiously long so I will copy and paste.

Question
I have connected my GPU to my DLP and I cannot get audio on my television’s speakers. How do I fix that?
Answer


This issue could be caused by a few things, so its important to describe the different ways to connect your GPU to your DLP.

Using the HDMI connector on the GPU to plug directly into the DLP HDMI input

For this configuration, check to make sure that you have connected the S/PDIF connector from the motherboard to the GPU. Please check with your motherboard manufacturer to ensure it has the correct S/PDIF connector.

If your motherboard does not have a S/PDIF connector and you wish to use the analog output on your motherboard to connect to the DLP, follow the instructions in Using the DVI connector on the GPU to plug directly into the DLP below.

Using the DVI connector on the GPU to plug directly into the DLP using a DVI to HDMI adapter

3D Vision ships with a DVI to HDMI connector that can be used to connect to the HDMI input on the DLP. In order to connect analog audio from your PC to the analog input on the television to use the television's speakers, follow these instructions:

1. Download the 3D Vision DLP Hotfix.

· Windows Vista 32-bit DLP Hotfix

· Windows Vista 64-bit DLP Hotfix

2. Connect your PC's analog audio into the analog input on the back of your DLP. Mode DLPs use left and right RCA audio inputs so you will likely need a cable called "3.5mm Stereo Headphone To RCA Adapter Cable" to connect your PC to the DLP.

3. Run the 3D Vision DLP Hotfix. Make sure you are running this as an Administrator on your PC

4. Follow the onscreen instructions to disable HDMI audio. Note that this DLP Hotfix will also toggle the HDTV Resize Desktop compatibility mode. For more information on that mode, please read this Knowledge Base article.

5. Reboot your PC.

6. If your DLP requires any changes to its settings, use your DLP remote to configure the audio input.

7. Start up your media player and adjust the volume to a comfortable level.

Cheers for trying to help, but the fix you linked to is for Vista only - I am currently using windows XP.

Unfortunately, I'm still unable to select HDMI audio output and have such still not fixed my audio issue.

Even i was facing same problem but i tried from one of website i found using googling. They had provided following solution which worked for me
In Control Panel, navigate to Sound and Audio Devices ->Audio tab.

Select Realtek HD Audio output and click 'Volume'
Speaker dialog will open. Then Go to Options -> Properties
select Mixer Device as any HD related audio and click OK.
That's it. Its done. Check with audio if its working
