Hi Clemens,
The most important thing was to switch the capture input to the I2S
channel 1 (The patch #13). Read the CS4245 datasheet carefully:
4.11
"The MUTEC pin becomes active during power-up initialization, reset, and
muting if the MCLK2 to LRCK2 ratio is incorrect in Asynchronous Mode or
the MCLK1 to LRCK2 ratio is incorrect in Synchronous Mode, and during
power-down."
Also there was other minor fixes. I had problems when I wrote
values to the CS4245 SPI memory at the starting point (had no any
effect), and I rewrote the SPI communication functions. Was there any
bug or the CS4245 was just muted - I can't exactly recall.
