How to read audio data in SAI example SDK for i.MXRT1050-EVKB

Hi all,

 

I am trying to read the audio data from the sai_edma_record_playback example where the program records and plays back audio data from the on-board MIC and process 16 bit samples of the data at 8khz (30 millisecond audio frames).

 

I have looked at the xfer.data buffer however it doesn't seem to contain the correct data.

 

Could anyone help me with this? (attached is the code, sourced from the SDK)

 

Many thanks
