Hello,
i am creating own accessory which should utilize line in/out from dock connector on iphone/ipod. Since i have iphone only, i did some tests and figure out that if u connect strait into line out pins on connector, sound will be still playing through built-in mic. I disassembled iphone dock to figure out that but it appears they using few chips on board with the help of which they somehow notify iphone when u plugging in/out a headphone 3.5 jack.
I did some heavy googling and was not able to find a schematic solution for this problem.
What i am asking is:
1) how to make line out/in to work on iphone without using dock station
2) how to do the same for ipods
