Hi All,

Is there any khadas board that has functioanl software support for hdmi earc as of now?
i know vim4 and vim3l have hardware support, but it’s not clear if the kernel support is there to make use of it.

Thanks!

Hello, in the dts configuration, I found the following corresponding configurations, I hope this information can help you
I will continue to look for information related to Amlogic and earc

vim4 dts configuration：

common\arch\arm64\boot\dts\amlogic\kvim4.dts

&earc {
	status = "disabled";
};

vim3l dts configuration：

common\arch\arm64\boot\dts\amlogic\kvim3l.dts

&earc {
	status = "okay";
};
