Windows 7 - No HDMI audio out with Windows 7

I don't have any sound from hdmi to my tv, picture works fine, use to work with windows vista and now that i have upgraded to windows 7 the sound is no longer available . I have rolled back the driver and did not work , i have also installed ATI HDMI Audio Device from realtek and still no sound. please help !

i set hdmi on default and test it , it shows no problems but does not play on tv

Try this. DELETE all the Audio Drivers using the same window you use to roll back your sound drivers(you must completely delete the sound drivers). Now you have no sound at all! GOOD. Turn off your computer, then turn it on again. Windows 7 will recognize your sound card and install it's own drivers. These work fine. You should have sound and vision through your HDMI cable. GOOD LUCK

Thanks for the respond but it still did not work, i uninstalled them and i restarted then the drivers installed automatically and still nothing,

btw i have tried windows + p switching to extend and duplicate and still no sound

Hi there
RCA Audio output should be no problem so long as you've got an AUX audio input on your TV

Use an adapter small jack plugged into headphone socket on laptop with audio rca plugs connected to AUX input on your TV.

I have fixed the problem , I had the HDMI cable connected to the TV on HDMI2 i changed it to HDMI 1 and I got the sound working.

I cant get my audio working on the TV (LG LE5300) as well. Attached you can see how my sound panel looks like.

My laptop is Acer Aspire 7720-6381 with NVidia 8600GT. I have tried removing sound drivers, installing the latest realtek drivers and nvdia drivers, but nothing is working.

I have a DVI to HDMI adapter on the laptop and HDMI port on the TV.

Any suggestions?
