Description
Hi, I am going through documentation to use the two I2S ports available and need to use one of them in Slave mode. I found earlier examples of people using two I2S ports together with one in master and the other in Slace with shared SCK and WS pins for the I2S peripheral.
I have been integrating the new library in my code and saw this documentation on the new library page:
"I2S Configuration
Master / Slave Mode
In Master mode (default), the device generates clock signal sck and word select signal on ws.
In Slave mode the device listens on attached pins for the clock signal and word select - i.e. unless externally driven the pins will remain LOW. This mode is not supported yet."
Is the Slave mode still being supported in the new library? I don't see any argument option in I2S class or begin function to include the mode of I2S peripheral. I have tested getting both those ports work by simultaneously capturing sound from mics on Port 0 and Port 1 by creating different I2S class objects and it works but has a lot of crackling sound and muffled sound on respective ones. Is there a default Master/Slave allocation or the Slave mode is not being supported for now? Thanks.

I have checked existing issues, online documentation and the Troubleshooting Guide

It is supported as long as the ADC provides all needed signals (BCK, WS, DIN)
cracks and pops are probably due to wrong configurations. You need to provide more info on your setup if you want us to be able to further help
