The code from another working project (slightly modified), but in this case it does not work. The sound card is not being created.

sound: sound { compatible = "simple-audio-card"; simple-audio-card,name = "TAS5720"; simple-audio-card,format = "left_j"; simple-audio-card,bitclock-master = <&dailink_master>; simple-audio-card,frame-master = <&dailink_master>; simple-audio-card,mclk-fs = <64>; simple-audio-card,widgets = "Line", "Line Out"; simple-audio-card,routing = "Line Out", "LOUT"; status = "ok"; simple-audio-card,cpu { sound-dai = <&sai3>; }; dailink_master: simple-audio-card,codec { sound-dai = <&codec>; clocks = <&clk IMX8MP_CLK_SAI3>; status= "ok"; }; }; &i2c2 { clock-frequency = <100000>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_i2c2>; status = "okay"; codec: tas5720@6c{ compatible = "ti,tas5720"; #sound-dai-cells = <0>; reg = <0x6c>; dvdd-suply = <&reg_sound_3v3>; pvdd-suply = <&amp_supplay_reg>; status = "okay"; }; };

Hello,

Do you have connected the board to this cards? You need to build the dtb and kernel to enable the device tree and know if the module if working.
