You will need a conversion cable. Easy enough to get, I ordered one myself last night! From MAPLIN (
a UK based outfit. If you live in the States/Canada, try radioshack.
You're looking for an s-video to Scart lead.
As for sound, I'm not 100% familiar with the FX5200, but it is unlikely to support sound, as it is a graphics card. However, just above or below your TV socket, on the back of your PC casing, you should have a mini jack socket for speakers. If you have a separate, third-party sound card, then you may have other options for sound out.
The s-video to scart cable should have a scart socket on one end, the other end should have an s-video plug and two co-axial cables (left and right channels).
To connect these L/R to a mini jack, you will need:
2 x *coaxial connectors* (about 75c each)
1 x *twin coaxial to mini jack plug (stereo)lead* (about $4)
Using the *coaxial connectors*, connect the two coaxial ends of the *s-video to scart cable* to the *twin coaxial to mini jack plug lead*. Plug the mini jack into the sound out socket on your PC.
This is the set-up I use myself on a PC with the Geforce4 440se. I have never come across a cable to do this job in "one piece". If you intend to use a high end stereo system to play back sound rather than your TV, then use the *twin coaxial to mini jack plug lead* to connect your sound output from the PC to the sereo system rather than the *s-video to scart cable*.
Believe it or not, this is the most straight-forward solution. It gives good quality transfer (s-video picture and full stereo sound). Use cables and connectors with goldplating on the contact surfaces for best quality (both picture & sound)
Alternatively, contact your nearest audio-visual hire company. They may make you an "all-in-one" cable to custom length, which may suit if this is a commercial installation which will be permanent. Warning though-they will charge you an arm and a leg!
