As per https://ez.analog.com/dsp/sigmadsp/f/q-a/536557/adau1452-asrc-can-it-work-on-32-bit-audio, the ADAU1452 has ASRCs which are limited to 24 bits in hardware. Is there such a restriction in the ADAU1467? I could not find any mention of supported formats in the datasheet but could have missed it.
EDIT: To clarify - I am talking about 16/24 bit PCM, with padding to 32 bits. A source I intend to use with ASRC only outputs 32 bit i2s, but I will only be playing 16/24 bit PCM through it.
