Hi,

 

IMX6Quad no output SPDIF signal, any config lost or error config? Could you help me to check? thanks!

 

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
   >;
};
