Hi Mark,
Regarding the balanced output schematic you advised, is it like the attached diagram?

I have spend hours trying make it work... It works now, but not as I expected. It is needed to re-pull MU-pin every time when freq is changed. If MU-pin is always on the GND, then I need to re-select USB-input to actualize freq. AUDMUTE (and DACRST too) which are on XMOS board are not help. There is "NOT LOCKED" promt until MU pin is not grounded at least for one time. I can actualizate freq manually by pulling MU to GND every time after freq of music changed. But to make it automatically "more or less" I can only by pulling MU-pin to DATA of I2S through 3kOhm. If more than 3k, then freq may not changed (depends on music). To avoid problems in SQ of music, I think that this resistor should be as much as can, because I don't want to solder any active splitter. If MU is connected to LRCK, then the freq is wrong (what "he" is doing there when showing me wrong freq ??? ), if connect to BCK\MCK - not works at all. Stupid method, but it works
I have wrong version of old XMOS pins functionality, but thanks of you Mark, you made me believe in myself

Unfortunately, there are some pops in music becsuse of that connection of MU to DATA. Most easiest way is to change XMOS to some modern version, OK
