I'm using a Nook tablet (8G) with the N2A card (8G). I downloaded Audio Evolution Mobile app and cannot seem to get the internal mic to record with it, however the internal mic does work on Tape-a-Talk audio recording as well as on the gStrings guitar tuner. I tried deleting those apps to eliminate possible conflicts, still no go. Any ideas on how to assign the internal mic as input? Also, any ideas on using an external mic through the USB jack on the Tablet? Thanks, R.
