Summary: For AD1836, it fails to play wav audio with particular settings by alsa lib tool

Details:

In 08r1 branch, for AD1836, use alsa lib tool to record a wav stereo audio with 8k sample rate and U8 format, then play it with aplay. It will fail.

This bug happens on both bf533-stamp and bf537-stamp.
