Premise: video section register I already configured, HDMI output no problem (only configure the video, there is no audio)
Process: I give SIL9022A I2S configuration I2S agreement after the audio output to display a video and audio, but the output is to restore the disappearance of the cyclical,
Register configuration was found among the audio part 0 x1f [7]=1, the output began to disappear cycle and recovery
Bosses, please this is what happened
