I know how it's supposed to work and I know it doesn't.

 ASUS EN9400GT/DI/1G (LP) GeForce 9400 GT 1GB 128-bit GDDR2 PCI
Express 2.0 x16 HDCP Ready Low Profile Ready

You also have the report from lspci. If can find on the net an Asus
graphic card that's better identified, provide the URL, I'll open the
case.

lspci told you that. Otherwise, I don't have a sound system. As I
said, I'm trying to connect it to a TV... which like all TVs has an
amplifier and speakers.

This is very plain in my first post:

"The plug had a molding problem and
one of the 4 holes was blocked. (The hole was just empty: no wire
going to it.) I opened it with a pin, installed it with the arrow
facing the closest part of the motherboard, reversed it, and, of
course, sound doesn't come out of the TV."

To the motherboard since that's where the sound chip is.

Not a keyhole. The s/pdif out plug has 4 pins.
