I got the following failed error,

[    0.723692] i2c-core: driver [wm8960] registered; 
[    0.729266] mt2701-wm8960 sound: ASoC: failed to init link wm8960-codec: -517 
[    0.736405] mt2701-wm8960 sound: mt2701_wm8960_machine_probe snd_soc_register_card fail -517

and sound is added in DTS:

sound: sound {
		compatible = "mediatek,mt2701-wm8960-machine";
		mediatek,platform = <&afe>;
		audio-routing =
			"Headphone", "HP_L",
			"Headphone", "HP_R",
			"LINPUT1", "AMIC",
			"RINPUT1", "AMIC";
		mediatek,audio-codec = <&wm8960>;
		pinctrl-names = "default";
		pinctrl-0 = <&i2s1_pins>;
	};

&i2c1 {
	pinctrl-names = "default";
	pinctrl-0 = <&i2c1_pins>;
	status = "okay";	
	wm8960:wm8960@1a {
		compatible = "wlf, wm8960";
		reg = <0x1a>;
	};		
};

The kernel is 5.4.68, so any idea on this question. Thanks for support.

Are you sure mt2701 is right for r64? Imho mt7622 is based on mt2712,not mt2701 (like r2)

Mhm,seems @skype uses same config

I have the same problem. @moore what’s your kernel version? Can you upload your full dts file instand of a patch? BTW, I boot openwrt from emmc. Thanks in advance.
