LCD TV over hdmi. Dual screen. Flashing/Blinking screen when hdmi audio is on.

[oblador]

Hi,

When I connect hdmi cable from laptop to my LCD TV, the screen eventually blinks/flashes. It becomes intermitently on/off.

It only happens when I enable hdmi audio.

How could it be fixed?

PS:
ubuntu 12.04
dell inspiron, 1525
intel 965

I tried the xorg edgers ppa, but the problem remains.

The screen is blinking when I plug the HDMI cable from laptop to TV and set the audio to HDMI audio.

Thanks.

I still wait for help.
