On mangOH board, WM8944 is used as audio codec to playback audio via PCM data. Here I have some questions:
since WM8944 is configured using I2C interface, there must be a driver thing to configure clock rate, sample resolution, data format etc inside the codec. Where can I find the driver code in Legato framework to make le_audio_PlayFile() work?
if such driver thing exists and our HW design needs a different codec chip, how can I modify/redo the driver under Legato framework?
