I'm running iOS and was excited when the app offered a menu option under the Advanced tab, to select High-Definition audio Output.
That was couple of years ago and yet it still does not actually enable the passing of High-Definition audio when my device is connected to a dac via the Phone Connection Kit.
However I've tested other similar apps which I use, and they do in fact pass High-Definition audio output, which suggests that this menu option is either just a place marker for an as yet to be implemented feature, or that the code is busted ?
Would really love to have it functional already ;-)
