Hi Ti Team,

We are facing issue when we play 8Khz audio file we are facing issue with the speaker.When same file is played in the PC,it is getting played.Below is the PLL settings used for the codec,

{ 12288000, 8000, 1, 7, 0, 7, 12, 128 }

I am attaching the audio file also for your reference.

Please let us know what can be the issue?

    Hi Prasanth,

    From your description, I assume you have MCLK = 12.288MHz and WCLK = 8kHz
    You can use the following clock settings, PLL is not needed:

    • NDAC = 1
    • MDAC = 12
    • DOSR = 128

    This will set FS = 12.288Mhz / (1*12*128) = 8kHz

    Best regards,
