Summary	0002055: Wrong Buffering for WM9715L Codec on QBlissA9 and QBliss SINTF
Description	Only 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 Reproduce	Play 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.
