I2S DAC output clock setting

Hi,

when I feed the I2S with PCM data, I found the audio speed is much more faster than it should be, but after I modified the board init frequency, it goes slower, I tried from 180MHz to 48MHz(the function I used is BOARD_BootClockFROHF48M/96M, BOARD_BootClockPLL180M();). So, what's the right way to configure the I2S clock? 

 

Best Regards,

Rui
