Hi,

My config and debug info as below 1~4

1. Playing command:

aplay -Dplughw:0,0 /mnt/test_wave/2448_1k_0dB_30s.WAV

2. Detected sound card as below:

card 0: imxspdif [imx-spdif], device 0: S/PDIF PCM snd-soc-dummy-dai-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

3. DTS:

sound-spdif {
   compatible = "fsl,imx-audio-spdif",
   "fsl,imx6q-audio-hdmi";
   model = "imx-spdif";
   spdif-controller = <&spdif>;
   spdif-out;
};

&spdif {
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_spdif>;
   status = "okay";
};

pinctrl_spdif: spdifgrp {
   fsl,pins = <
   MX6QDL_PAD_GPIO_17__SPDIF_OUT 0x1b0b0
   >;
};

4. kernel config:

Hi br

one can check linux configs described in sect.7.4.4.1 Menu Configuration Options

attached Linux Manual and dts example

imx6qdl-sabreauto.dtsi\dts\boot\arm\arch - linux-imx - i.MX Linux kernel 

Recommended to try nxp linux from codeaurora repository

linux-imx - i.MX Linux kernel 

Best regards

Hi igorpadykov,

It's OK after updating dts

   assigned-clocks = <&clks IMX6QDL_CLK_SPDIF_SEL>,
            <&clks IMX6QDL_CLK_SPDIF_PODF>;
            assigned-clock-parents = <&clks IMX6QDL_CLK_PLL3_PFD2_508M>;
            assigned-clock-rates = <0>, <227368421>;

Thank you!
