Hi!

I connected a TV set to an HDMI connector on my sound card. There is video
output,
but no sound.

I would say it depends on how your TV presents itself.

I have one of my NVIDIA ports hooked up to the HDMI input of my home receiver (called a home theater unit now), that handles siwtching between
devices -- it has a TV out -- to my flat screen.

Anyway, the Nvidia has always detected a video display through it
(but always PNP)...latest drivers and card detect the audio system as a 8 channel output device -- it's not in my kernel or driver -- but in the device -- it splits the sound off and send the video signal on.

Wasn't until latest set of drivers with newer graphics card that it could detect the digital audio channel through HDML....

My card is a GTX590...

(drives up to 4 displays) and several digital audio output devices are associated with it -- probably one for each video port.

Of course I'm running it under Windows...so who knows what would happen under linux...
