Try solve problem like-- 1.Use SPDIF input direct from TOSLINK module 2.Use I2S-GND/D1 input also from TOSLINK module 3.Reset the BII on board But same as before - out of sound Thanks

On a hot Placid or on a cold one? 5.25V when it's hot is a good measurement for a Placid. 5.45 when it's hot means you're likely going too high for the Tridents when the Placid is still cold. Also, please note you're powering shunt PSUs. A shunt of 50mA is enough, more just generates extra heat.
