DVI to HDMI cable questions?
Key parts involved, fluid 46"/8800gts/ dvi to hdmi 25' cable(yes I understand that it doesn't carry sound)/ aux 3.5mm(from pc) to L and R rca sound wire to tv.

Originally s-video and aux 3.5 to L n R rca works fine on tv.

What I did (dvi to hdmi 25' cable), put dvi end on 8800gts then plugged hdmi into tv (tried all 3 hdmi inputs on tv) picture is great, works perfectly.

Aux 3.5mm to rca sound just won't work with the hdmi plugged in (tried other aux inputs , no sound but there is a signal coming through the wire) .

What i'm wondering is am I trying to do the impossible, does the dvi to hdmi cable force the tv to use audio over hdmi that isn't there because it's a dvi connection?

Is my only option to put a small set of pc speakers next to the tv and run them out of the pc? This pc to tv stuff is new to me.

depends on what version of HDMI cable (1.4a) or DVI ???

Might be easier just to do a slight upgrade to the vid card for one that supports HDMI audio (there is probably an analog audio connection on your 8800GTS, but I'm not sure if it will pass the audio through DVI to HDMI).

Did you look to see if you had audio input config options in your TV setup menu? It's a long shot, but worth checking for if you didn't already.

I'm not trying to pass audio through the 8800 just from on board mobo, it's looking alot like the tv locks or ties the audio to the hdmi port on the tv and won't allow any other aux inputs to feed sound to the tv while the selected hdmi port is in use.
