Hello Champs,
There is a PCM3168APAP on J721EXCPXEVM and the PCM driver is in j721e-evm.c. Customer now is using TLV320AIC3109 and he modifies the dts, does he need to modify the j721e-evm.c file?
Is there some example for TLV320AIC3109 sound driver and dts file？
Thanks
Regards
Shine
Hello Keerthy,
The sound card can be detected after modifying the driver and dts.
TDA4VM can communicate to audio chip via IIC. The driver are mounted and installed successfully. 
But after mounted successfully, there is no MCASP clock output signal and no sound when running aplay or speaker-test.
Below is the tlv audio device dts configuration
tlv320aic31xx: tlv320aic31xx@18 {
compatible = "ti,tlv320aic3x";
reg = <0x18>;
reset-gpios = <&main_gpio0 111 GPIO_ACTIVE_HIGH>;
/* C_AUDIO_REFCLK2 -> RGMII6_RXC (W26) */
clocks = <&k3_clks 157 371>;
clock-names = "scki";
/* HSDIV3_16FFT_MAIN_4_HSDIVOUT2_CLK -> REFCLK2 */
assigned-clocks = <&k3_clks 157 371>;
assigned-clock-parents = <&k3_clks 157 400>;
assigned-clock-rates = <24576000>; /* for 48KHz */
AVDD-supply = <&vsys_3v3>;
IOVDD-supply = <&vsys_3v3>;
DRVDD-supply = <&vsys_3v3>;
DVDD-supply = <&vsys_3v3>;
};
Below is the driver:
