i also would like to learn a way to record both sides in touch diamond.

i have tested softwares named; Resco Audio Rec, Vito AudioNotes, PMRecorder. But they seemed all same to me, they record only through talking microphone.

I've read in some places that this is a hardware limitation, but basically sound can go to bluetooth devices so i guess it can't be a hardware limitation but a software.
Hope someone can find what trick microsoft used for us not to record our calls.
