[PROBLEM] RPi 4b connected via I2S to SABRE ES9038Q2M DAC POPs at manual Track Change

@vinnn  comment re 'USB is a asynchronous data interface' is pertinent..

I do not see that the board has a USB input though you would be able to add one using an xmos USB to i2s.

This works on all my Es90x8 boards for click free operation ;-)

Your current ES9038q2m hardware is for voltage drive output from the Ess chip.
A step up in performance is to use current drive...the thread you referenced has much discussion on this.

This Es9028q2m board using current drive (note the 4 opamps vs 1 on your board) bests my Es9038q2m (using voltage) drive easily

Another alternative if you wish to maintain an i2s connection chain rather than USB is a hardware resampler..
