I migrated from rk3399-roc-pc to rk3399-roc-pc-plus. After porting the audio driver, I found a problem, that is, when the HDMI is not connected when the power is turned on, the headset audio works normally, but it is plugged in when the power is turned on HDMI.the headphone audio driver does not work properly. When I tested the audio decoder chip, I found that I2S is working properly, the i2c register is configured correctly, everything is the same as when HDMI is not connected, but there is no sound, and there is only noise when the headphones come out. Or there is no sound.can you give me some advice?
