TPS54040: Vsense Noise

Part Number: TPS54040

Hi,

I have some queries regarding IC TPS54040 as I am using it for our sound card design.

I observed that there is a high peak noise at 14.5Khz when we probe at the Vsense pin (refer to  attachment)

Not sure what causes this abnormal behavior and hope you could assist and enlighten me. below is the components that we are using for the IC.
