There is a note for the register "Digital Audio Interface Format
(Address: 0000111)" but I cannot find is this true for all formats or
probably only for I2S. If it's only for I2S then this would explain as
MCLK is 12 MHz in OSK5912.
"2. In master mode, BCLK = MCLK/4 for all sample rates except for 88.2
kHz and 96 kHz. For 88.2 kHz and 96 kHz sample rate, BCLK = MCLK."
Do you have possibility to measure this with an oscilloscope that are
there more bit clock cycles than 32?
