Hello,
My audio hardware : SAI (CPU) is the master for audio ADC and audio dac.
Is it possible to set audio_pll1_out frequency so we could play\record in all common audio sampling frequencies in the bands of 8 kHz, 16 kHz, (32 kHz - 44.1 kHz - 48 kHz), (88.2kHz - 96kHz), (176.4 kHz - 192 kHz).
With 16bit/24bit/32bit ?
Currently I found it impossible to set audio_pll1_out to such a frequency that support all.
for example if I set audio_pll1_out (in dts) to 24576000 I can :
- record/play with all 48K multiply/dividers (8/16/32/48/96/192) on 16bits and 32bits .
But for 48K/96K/192 I can't run at 24bits.
You can find attached clk tree & The error I get while trying for example 48K --> 24 bits
--> Why it should be fix frequency and not PLL that can set the request rate sample on the fly ?
Appreciate your help,
Moran.
