我们在35.1上适配alc5639，以上两个dtsi文件为修改的内容，刷入系统之后查看到如下结果：

，然后插上耳机，测试并没有发出声音。麻烦帮我们检查一下在哪里出的错误？谢谢！

您好！
这是我们开机打印的日志信息：

我们适配的rt5639还是没有出声，请您提供一些意见！谢谢！

Hi,

First, ensure pinmux is set for relevant I2S and aud mclk. Guide for pinmux setting is available at Jetson Module Adaptation and Bring-Up: Jetson Xavier NX Series — Jetson Linux<br/>Developer Guide 34.1 documentation

Second, the dts override seems to be wrong instead use below as reference. Recompile kernel dtb and flash and check if the codec/card are being registered

/ {
	i2c@3160000 {
		rt5640: rt5640.8-001c@1c {
			compatible = "realtek,rt5640";
			reg = <0x1c>;

			clocks = <&bpmp TEGRA234_CLK_AUD_MCLK>;
			clock-names = "mclk";

			realtek,dmic1-data-pin = <0>; /* RT5659_DMIC1_NULL */
			realtek,dmic2-data-pin = <0>; /* RT5659_DMIC2_NULL */
			realtek,jack-detect-source = <7>;

			/* Codec IRQ output */
			interrupt-parent = <&tegra_main_gpio>;
			interrupts = <TEGRA234_MAIN_GPIO(AC, 5) GPIO_ACTIVE_HIGH>;

			#sound-dai-cells = <1>;
			sound-name-prefix = "CVB-RT";

			status = "okay";
		};
	};

	sound {
		nvidia-audio-card,widgets =
			"Headphone",    "CVB-RT Headphone Jack",
			"Microphone",   "CVB-RT Mic Jack",
			"Speaker",      "CVB-RT Int Spk",
			"Microphone",   "CVB-RT Int Mic";

		nvidia-audio-card,routing =
			"CVB-RT Headphone Jack",     "CVB-RT HPOL",
			"CVB-RT Headphone Jack",     "CVB-RT HPOR",
			"CVB-RT IN1P",               "CVB-RT Mic Jack",
			"CVB-RT IN2P",               "CVB-RT Mic Jack",
			"CVB-RT Int Spk",            "CVB-RT SPOLP",
			"CVB-RT Int Spk",            "CVB-RT SPORP",
			"CVB-RT DMIC1",              "CVB-RT Int Mic",
			"CVB-RT DMIC2",              "CVB-RT Int Mic";

		nvidia-audio-card,mclk-fs = <256>;
	};
};

&i2s5_to_codec {
	link-name = "rt5640-playback";
	codec {
		sound-dai = <&rt5640 0>;
		prefix = "CVB-RT";
	};
};

Thanks
