thanks a lot! You made my day (c: Using EP5 for feedback makes it working. So I now get the data out even in async mode. Currently I have a problem left that channel assignment jumps here and then. Probably a buffering issue... Also neither a SRC4192 (sample rate converter) nor a PCM1794 (dac) seem to be able to understand what I am sending right now... Not sure why. Looking at the measurements it really looks like a proper I2S signal.
Can you send oscilloscope screenshots? Which data format are you using?
Sure, attached you see a capture while running speaker-test to generate a 1khz sine wave on one channel. (Blue: BCLK 1,536MHz, Yellow: LRCLK: 48kHz, Green: I2S data) If you want to see more/other captures just let me know what you need.
Signal is 48kHz 16Bit. As it's I2S it is MSB with 1 BCLK-Cycle delay.
