OK now have checked, and the only way is either to use the optical out with a DAC, as I suggested before, or to use one of the Scart sockets, which are both in/out types, with a cable such as this.
, though you'll only be using two of those plugs - the red and white audio out ones.
It's about £15 from Maplin
here
Or you could just use one of these
, again from
Maplin, with a pair of conventional stereo interconnects.
The adapter's about a tenner, and you could get a 5m interconnect run for the right side of £20, which I reckon would be more than good enough for this hook-up.
The DAC is one way to go, but it's the expensive option and I suspect the digital output from the TV won't be all that great, so it might be a lot of dosh to achieve what you could otherwise do much more inexpensively in analogue.
Similar adapters are available from a number of retailers, both online and in the real world!
