1. &acodec {
   
2.     rockchip,micbias1;
   
3.     rockchip,micbias2;
   
4.     rockchip,en-always-grps = <0 1 2 3>;
   
5.     rockchip,adc-grps-route = <1 0 3 2>;
   
6.     /delete-property/rockchip,loopback-grp;
   
7. };
   

复制代码

1. 如果rockchip,adc-grps-route是<1 0 3 2>（表示MIC3为0通道），就把vad的rockchip,det-channel改成0
2. 接调试串口看log

3. 如果唤醒太灵敏，参考文档doc目录下的《Rockchip_RK3308_Developer_Guide_Linux_VAD_Hardware_CN.pdf》，《Rockchip_RK3308_Developer_Guide_Linux_VAD_Register_Configuration_CN.pdf》。
