No HDMI audio out with Windows 7

Great, after downloading the intel driver, i now have lost the picture on the input tv screen. It is fine on the laptop but bearly readable on the tv, really white..... The only plus is i now have the sound for the hdmi. I have since downloaded the graphics driver from dell, and it said that it was an older version than the one installed (the intel site one), hoping it would fix the tv problem but didn't.. this is really frustrating as i'm and too good with computers.
does anyone have any ideas????

But it WORKS! My HDMI sound is back but the screen on my laptop in barely readable which is opposite of your case. I'm getting a heavy reddish hue on my laptop screen but I don't care. I own a Inspiron 11z.

I think this all can be traced to Windows Update as I remember selecting an optional update for my Intel Graphics and Realtek Audio couple weeks back which probably borked the HDMI out. I'll play around with the graphics drivers to see if I can get the anomaly straighted out.

Much thanks to Kivanc for the tip btw.

EDIT: Got the Red glare issue fixed. Right click desktop>select graphic properties>pulls up the new Intel Graphics Control App>Goto Color Enhancement and select restore to default.

For some reason the new driver set mine to a high red gain on the built in display. Hope this helps.

To the extent this helps anyone - I also had the same problem discussed in this thread (I have a Sony Vaio VGN-FZ21Z, with a sigmatel high defintion audio and Nvidia Ge FOrce 8600M GS), and unfortunately none of the solutions worked for me.

HOWEVER... I recently tried again and this time got the HDMI audio to work... what i did was uninstall IDT audio from my list of programmes, and then restart the computer ! naturally windows reinstalled a high definition driver and this driver allows my now to hear audio through my hdmi!!!

This was purely discovered by accident (as I was going to try to stop windows installing a generic driver and try to install an updated IDT audio file - but as windows 7 was too quick for me to stop it - I stumbled accros this 'solution').

I hope this helps others with the same configuration... and Happy holidays

UPDATE 28/12/09 - With this new generic driver I now no longer can use the builtin microphone on my computer... very annoying - the webcam works (in MSn but not skype?) but the microphone doesnt work (in any programme) - any suggestion would be warmly welcomed!
