I uses SGTL5000 with i.mx6SL using Android 4.4.2.
Above audio codec can play wav file without problem.
While recording MIC input to wav file, audio broken sometimes.
for example, just record about 10 seconds but just plays about 8 seconds. that means some region plays shortly than expected time, 2 second voice just omitted(compressed).
we just no connected VDDD.
Please let us know where should I check.
