Audio Systems: Component audio to DVI-I audio adapter, hd component cables, component to vga adapter

Question
In about the last year I ordered an expensive phillips plasma TV off the internet.

Now, in try to connect HD component cables I've realized that the TV uses a DVI-I input for HD.
In the manuel it stated that I would need a Component to VGA adapter then another VGA to DVI-I adapter.
I was actually able to find a Component to DVI-I adapter and it works fine however I cannot locate a Component to DVI-I audio adapter.

The manuel doesn't stated it but it has a diagram of the component audio being plugged into and adapter and then into the TV so I must assume that it exists however I have been unable to locate any at all.

So my question is, is it possible and do you know of any in a reasonable price range.
If it's not possible can you tell me of any alternatives.

Answer
I would be very suprised if the Plasma TV doesn't have component inputs (RCA) red, green & blue. If so the quality of picture should actually be marginably better than DVI. If you have those connections then use 5 high grade RCA cables - Component TV in R,G,B and left and right audio of the same TV input. DVI is an expensive solution for people who quickly want to connect their TV without a bundle of cables. I never use in in professional installations
