Hello,

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

    Hi haye.dorian,

    Could you please precise the range of ''big size buffer'' and small ones?

    Is the issue faced with Cube example or your own code?

    This helps to check deeply the reported issue.
