STM32F4Discovery Audio play communting noise

When I use the function to play sound (BSP_AUDIO_OUT_Play or BSP_AUDIO_OUT_Changebuffer) I heard a noise like a commutation. This noise is not really a big problem on big size buffer but when I read small buffer this noise is reapeated often.

So my question is : does a solution exist to avoid this noise ?

Thanks for any support
