Yes, that looks suspicious, especially because it doesn't only affect the lower bits. What do you need this sample rate converter for, anyway? Can't you feed your signals directly to the DAC? FMT0 and FMT1 should both be set to 0.
You mean OFMT0 and OFMT1? Imho they should be 1,0 for I2S. Or did you refer to the DAC? In that case FMT0 and FMT1 both are set to 0.
Jup, I was talking about the DAC.
I have the SRC in there to be able to always feed that DAC with 192kHz, as it performs best in that mode and allows usage of a slow roll-off filter then. Anyway, I tried to directly feed the DAC module as well, but it does not produce any output so far... Not sure what's wrong there. As the dac is a current output dac, I am not sure whether it really does not output any signal, or if the current->voltage conversion does not work.
