Thanks for that pic and very interesting diagram, DonalDuc - meanwhile the adapter I referred to above...
has arrived and it's the wrong way round (large plug to small socket - which, now I look at the description, is what it says. Silly me. I'd still rather find that kind of adapter (one with a short lead) rather than the one-piece kind.I've now seen the other thread here re audio and 4 pole seems indeed to be required - http://www.calculatorking.com.au/pda...-5-to-3-5.html seems to be the kind of thing. I'll get one and report back again.
