      On AM62D,

      When we do aplay and record together, sampling rate become half.

      A) Steps to reproduce

      1. Connect J1A to mic
      2. Connect J3A to speaker
      3. run command : arecord -c 4 -r 48000 -f S32_LE - | aplay -
      4. Observation: play is running with approx half sampling rate

      B) Another way to reproduce 

      1. Connect J1A to mic
      2. Connect J3A to speaker
      3. Play audio on J3A in background
      4. Record audio
      5. stop recording 
      6. Copy the recorded wav file to host machine
      7. analyze the audio with Audacity
