somehow it looks like the PCM1789 generates noisy background noise with some frequency loss or drift. the volume is also very high. i observed the signal right coming out of PCM1789. I am using hardware control with I2S audio(tried also left adjusted) format, 48kHz sampling, master clock of 256fs and 512fs and 64fs bit clock.
is there any issue with PCM1789? is there any way decrease the loudness and solve the problem of getting better audio frequency response out of it?
