1. Can you get audio from the s-video out of your gfx card? The seller told me I could but I find that hard to believe.
No!
2. The seller mentioned that the white o/p connector on the cable is useless cuz all audio from the PC is mono. Basically only red and yellow work. Another thing I can't understand.
LOL...
The S-Video (7pin) out has two types of output available...RGB component (3 RCA jacks, which is what you have) or Y-Cr (luminace and Chrominance) (2 RCA)
3. I tried connecting the red and white connectors to the L and R audio inputs on the TV and the yellow connector to the A/V in. I set the TV as the secondary clone display in display properties. But wasn't able to get it to work. Any ideas if I have missed any steps?
It won't work of course....
1- If your TV supports RGB input, connect these three cables there,
2- if it doesn't, but supports a Y-Cr in, get a S-Video to 2 RCA jack a, and connect them there
3- If it has only composite video in, what you need to do is get either a S-Video to single RCA cable (difficult to find) or connect the Y cable to the Compoite In, and short the Cr wire to the Y wire through a 47 pf capacitor....Be aware that this gives you the lowes quality piicture signal
Y------------|- RCA In
- = (47pf)
Cr-----------|
tried making a ASCII ckt diagram there, but doesn't seem to come out right..hope you got the idea though
