The sound node was not generated before because the codec driver failed to load. Now the node is generated and the mclk signal can be detected. However, when I use the following command to play, there is no signal in i2c2, and the signal comes out from the following pin. from i2c4 and not from scheduled i2c2
$ amixer -c APE cset name=“I2S2 Mux” ADMAIF2
$ aplay -D hw:APE,1 xxx.wav
