Default irs2092 click and pop suppressor not working.

On power down I am getting a huge pop through the speaker.

Have tried from 10uf to 150uf on the CSD pin and it makes no difference, it just slows down power up.

Did some experiemnts with different capacitor values and seems I was going the wrong way. the 2092 requires a smaller capacitor than on the datasheet.
