Core 1 panic'ed in streams-i2s-i2s-2 example

[DrNoobBanana]

thank you for your great library

I have a PCM1808 ADC and a PCM5102 DAC and an ESP32 WROOM 32. I connected everything as was suggested in the READ ME file. and when I upload the sketch, it just keeps printing this:

I also have a cheap analog microphone which is connected the left input of my ADC.
the streams-i2s-serial example worked fine with my ADC, which requires an MCLK (SCK) input. my DAC also has a SCK pin but IDK where to connect it since it is not mentioned anywhere in the example.

Make sure that you use an actual version of the core and all libraries and if you then still get a Backtrace you need to analyze it yourself to identify the the code line that is leading to the crash

Apart from this follow the advice given in the Wiki!
