Some troubles in 176 and 192 sample rates. devboard didnt see signal from toslink.
may be is special params for spdif for work in 192?
same question for adau 1452.
yes trough the 2 registers SPDIF_TX/RX_MCLKSPEED to be configured in sigmastudio.
there is a post about this on engineer zone but can't find it anyore
