Normally DMAs are not "fighting" for resources. When you upload your project here or at least the DMA settings and setup calls we all can have a look at and check for mismatches.
To do so: Build -> clean Project
File -> Create Workspace Bundle (minimal)
and finally upload the resulting archieve here.
It is working now after I corrected DMA Td configuration.
Now I can visually analyze ADC I2S output with my LogicPort logic analyzer.
