楼主
个人感觉需要修改DTS
rt5640-sound {
compatible = "simple-audio-card";
simple-audio-card,format = "i2s";
simple-audio-card,name = "rockchip,rt5640-codec";
simple-audio-card,mclk-fs = <256>;
simple-audio-card,widgets =
"Microphone", "Mic Jack",
"Headphone", "Headphone Jack";
simple-audio-card,routing =
"Mic Jack", "MICBIAS1",
"IN1P", "Mic Jack",
"Headphone Jack", "HPOL",
"Headphone Jack", "HPOR";
目前MIC只有IN1P，而耳机的MIC是IN2P，可能要增加一个MIC吧，或者2者取其一。
