title: Line stereo/2-channel recording
body: <p>Are there any Android devices available that support multi-channel (stereo) recording via line-in?</p>
  
  <p>With the devices I tested (Nexus 4, HTC Buzz, Motorola Xoom ..), it is possible to set AudioFormat.CHANNEL_IN_STEREO, but I only receive one active channel. </p>
  
  <p>Is this a gerneral limitation of Android due to licensing issues or is this depending on the manufacturer/hardware, i.e. there is only one A/D converter for input or some such?</p>
  
  <p>Any experiences, thoughts or ideas on this topic? </p>
