Hi guys,
I have a DAC with a COD and s / pdif module and it has a crackle output when I want to listen to an ultra HD song like Roger Waters by amazon HD but not if I listen to Patricia Barber. The only difference between them is that the first is 24bits / 192khz and the second is 24bits / 96khz. When there is a crackle the LEDs d1, d2 and d4 turn green and red, if I place my fingers on the wires between the s / pdif module and the dac the crackle stops. Someone can help me? thank you!

That's a pretty interesting problem. Can you post a picture of your setup and wiring?

My first guess would be a loose connection, or a wire routing issue, but it is hard to say. 192kHz is a noisier bitclock (higher frequency) so it may be highlighting an issue you don't see (hear) with 96kHz.

Nothing jumps out. I would try removing the I2S wires completely, and then putting them back in, making sure they are spaced out from one another and that they are well secured. I would also try to move the power wires for the modules as far fro the I2S lines as possible.
