Before you buy the cable try plugging the tv into the computer and run
#lspci and see if the hmdi hotplug pin triggers udev  and an inode for
the device is created. If it is, you should be able to capture and
multiplex the sound back into the hdmi transport layer. VLC wil do
transcoding on the fly and can sync audio, dealing with any delay. I
don't have a hdmi TV so I've never tried but I have helped people
reduce RF noise in their Audio systems using variations of th snippet
below, depending on what sound devices show up in aplay -L.

I posted this shell code bit in an earlier thread, #lspci and udevadm
should provide information in aid of the device mappings which must be
be done.

tvtime | arecord -D hw:1,0 -r 32000 -c 2 -f S16_LE | aplay

In this example tvtime is pre-configured to address /dev/video0
however the tv time signal is also sent via arecord to the soundcard
with an assigned bitrate and information on the type of card used. The
signal then piped through aplay and sent to the speaker output.

The lack of corresponding 1 to 1 pin assignments on your Nvidea card
means you have to play around a bit to find the proper device to
attach to, but it shouldn't be that difficult if you play around a
bit.

Check your paperwork for the TV. Look for a GPL license. I think
anynet runs on a GPL'd webserver. which means that some form of Linux
is in there.

Of course if its got optical audio out, buy the cable and use that. I
think you can even buy an optical dongle for standard sound card
digital output.
