Not sure if this has been asked for before, but personally I think it would be a great feature to allow for both a A2DP connection and still allow for a device to be wired in via the 3.5mm jack. This could 'free up' the A2DP connection for another use as well (if say, one is wiring in a nano for music).
I figure this would also mean muxing both the A2DP stream and wired streams, as both would technically always 'be on'.
Thanks in advance
