IMX6DQ SSI in I2S Master mode and audio noise

[amsaleem]

We have a custom board with IMX6DQ processor, and the board configuration is similar to the SABRE Board. It has SSI in I2S master mode configuration. We are able to capture and pay the audio. But there is some background noise while playing audio. Below given is the audio codec and SSI configuration from dts file.

regulators {
compatible = "simple-bus";
reg_audio: regulator@2 {
compatible = "regulator-fixed";
reg = <2>;
regulator-name = "wm8962-supply";
};

sound {
compatible = "fsl,imx6q-extron-tlpx25-wm8962",
"fsl,imx-audio-wm8962";
model = "wm8962-audio";
cpu-dai = <&ssi2>;

};

pinctrl_audmux: audmuxgrp {
fsl,pins = <

};

Is there any issue in dts configuration? Looking for your help.

Thank you
