Hi,
I use RT5639 on the R32.3.1 version of Jetson Tx2, I add data in dts,

and modify the program in kwenwl / nvidia / sound / soc / tegra-alt / machine_drivers / tegra_machine_driver_mobile.c
static const struct of_device_id tegra_machine_of_match = {
{.compatible = “nvidia, tegra-audio-t186ref-mobile-rt5639 / 40”,
.data = & soc_data_tegra186}
The sound card hardware has appeared, but the sound is accompanied by a strange noise like metal or broken sound. What adjustments should be made?
