IMX6al audio only one channel has sound. MCLK is 11.2896 MHz, SCLK is 2.82 MHz, and LRCLK is 44.1KHZ.
Normal playback is left channel sound, right channel no sound,If I change register 23 of ES8388, the left and right data exchange bits, there will be no sound in the left channel and sound in the right channel. It has been proved that the hardware should be ok.I measured LRCLK and DSDIN through oscilloscope, and found that there was data transmission only when LRCLK was low level, but there was no high level.I have set up the route in es8388, I don't know what else need to set up in imx6ul.
