No Audio via HDMI between My Sony Vaio and TV

Hi to all. First, sorry for my bad english. And sorry if I wrote in a wrong section. I have a Sony Vaio VGN-FZ38M laptop with NVIDIA GeForce 8400M GT GPU. This pc have an hdmi output. The issue is the following: when I connect pc to tv with HDMI, video is ok but audio is not reproduced from tv (only from pc). I have formatted pc and reinstalled OS, disinstalled and reinstalled Nvidia driver (both old and last versions) but nothing. I tried with other two tv with hdmi, I tried with some different hdmi cable but nothing. In Playback devices, there are only two voices:
Speakers / Headphones (Default Device)
Digital Audio (HDMI) (Unconnected)
The audio driver of my sound card is SigmaTel High Definition Audio CODEC (at version 6.10.5614.0). I tried in various ways but this voice is always on "Unconnected".
Can you help me? Is impossible to have an HDMI output and can't use it at 100%. Thanks to all.

After yesterday was impossible to set HDMI connection as default because in Playback Device the voice Digital Output (HDMI) was always on disconnected and was impossible to connect it. But before some attempts (for 5 months), I tried to uninstall audio driver and not install nothing (the audio drivers for my model of pc are SigmaTel High definition). Windows automatically install yours drivers and the HDMI output finally work great. It was all the fault of SigmaTel drivers. Thanks for your help. See you next time
