it seems that SigmaDSP doesn't set the ADAU 1442 to the desired 96 or 192 kHz.
If anything is set to 96 kHz, the 1442 outputs send every 24-Bit Data twice, so the real resolution stays at 48kHz.
With 192kHz every Data is send four times.
It doesn't matter wether i use the ADCs or do program the ADAUs signa lgenerator, the problem stays the same.
With 48kHz erverything is fine.
The 1442 is programmed with a MCU via exporting the SigmaDSP header files. The MCU programms the 1442 using I2C.
That does work.
ADC/DAC are connected via standard I2S, Clocks are
System : 24MHz (ADAU Clock Out)
Frame: 96 kHz/192kHz
ADAU clock is Master both for ADCs and DACs
Jumper for PLL0 is fitted (PLL0 = low)
PLL2: doesn't matter wether Level is High or Low
PLL1: can't be low, DSP crashes if Level is set to low
quartz crystal: 12 MHZ
I tried to fix that Problem for two days but had no success.
