Hi zha ye
About your questions:
question1: The sgtl5000 initialize the end, it's i2s_out pin always generate a signal to MCU , although i have input nothing
Yes, as long as the sgt5000 is correctly config, it should continue getting signal in the input and i2s_out always will generate signal.
question1:My MCU have setup to slaver, DMA reciver mode, this also can't recive nothing.
If you have configured your sgtl5000 as slave, then MCU should be your master in the i2s communication. It is possible to use the MCU as slave, but then your sgtl5000 must be the master.
Hope this information could help you.
Best Regards
