Summary0002055: Wrong Buffering for WM9715L Codec on QBlissA9 and QBliss SINTF
DescriptionOnly left channel gets buffered. Buffering gets done for left and right channel but only from left channel of the pcm stream. Due to this wrong buffering the sound file gets played to fast and frequency gets doubled.
Steps To ReproducePlay Sinus or Square Wave with a static freq. Output of codec is the doubled frequency.

Additionaly: Separate channels with diffrent waveforms for left/right channel.

Codec was not in two channel mode.
Buffering is ok now, but there is a noise on the right channel.

Initialize codec with Two-Channel-Operation enabled in SCR register of SSI Interface.
