Greetings I have a Sony Vaio system with Nvidia 9600MGT and HDMI port I keep my hdmi plugged in as a watch dvd's through media center, on my 32" Sharp. The sound taskbar used to automatically switch from hdmi to the laptop's soundcard automatically. It doesn't any more. Basically, if I turn off the hdmi mode on my tv, it used to switch from hdmi sound output to laptop's card. When I activate hdmi again, it would automatically switch to hdmi output. I'm using the Windows nvidia drivers provided via windows update.

Would appreciate any possible help on this. Thanks. PS: I'm pretty sure I remember this happening in Vista as well.

Chadi_W7,There are some newer drivers from the Nvidia website that are specific to Windows 7. You might want to give those a try.

Chadi_W7,Nice. Well, you can always try the Windows Vista drivers from the VAIO site and install them in compatibility mode.

VAIO computers are notoriously stubborn about working in any environment which hasn't been expressly authorized by Sony. I think any drivers which you happen to catch via Windows Update are going to be your best bet.-Alex

Chadi_W7,Have you had any luck with this?
