Hi I prefer to listen to my iPad audio and MBP audio through the same headphones so take a line-out from the iPad into the line-in on the MBP and use LineIn to pass this through to the headphones. I'm using an old iPhone 3G dock (with the top-case and weight removed) to allow me to do this and charge my iPad at the same time. I bought one of the many combo cables from ebay that should allow me to do this: http://www.ebay.co.uk/itm/320664814989?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_5007wt_1017 but this doesn't charge properly, even when plugged into an iPad 3 A1357 10W USB charger presumably because the USB cable isn't of an adequate spec to draw enough current . Anyone sourced one of these that works with an iPad 3? Anyone using the SendStation adaptors on a New iPad (3)?
